As an oil-soluble antioxidant, tert -butylhydroquinone (TBHQ) is widely used in edible oils, so accurate control of its content is significant for food safety. Here, a CdIn 2 S 4 /SnIn 4 S 8 S-scheme heterojunction structure was constructed by in-situ growth of smooth flower-like CdIn 2 S 4 on rough three-dimensional SnIn 4 S 8 microspheres via a one-pot co-precipitation technique. Subsequently, TBHQ was combined with CdIn 2 S 4 /SnIn 4 S 8 /GCE, and the photocurrent signal was significantly increased, which could be detected in the concentration range from 0.02 to 150 μM, with the limit of detection as low as 2 nM. The reaction mechanism of CdIn 2 S 4 /SnIn 4 S 8 composites was verified by using density functional theory calculations. Meanwhile, the reason for the outstanding detection of TBHQ was investigated by exploring the electrostatic potential and the related redox potential. In addition, the sensor was demonstrated to have excellent recoveries by comparing UV–Vis spectrophotometry for the detection of TBHQ in peanut oil, canola oil, blended oil, and soybean oil.

Photocatalytic oxygen reduction reaction (ORR) offers a mild and cost-effective approach for hydrogen peroxide (H 2 O 2 ) production. However, its practical application is significantly hindered by rapid charge carrier recombination and insufficient O 2 adsorption capacity in photocatalysts. To address these limitations, we developed a strategy involving the creation of S-vacancy-rich CdIn 2 S 4 (S v –CIS) to facilitate charge separation and subsequent deposition of Au nanoparticles on its surface (Au–S v –CIS) to strengthen O 2 adsorption. The results suggest that the optimized Au–S v –CIS achieves a significantly increased H 2 O 2 production yield of 2542 μmol·h·g −1 in 10%-ethanol/water solution, which is about 12.8 and 1.7 times higher than that of pure CIS and S v –CIS. Comprehensive characterizations including photoluminescence spectra, time-resolved photoluminescence spectra, transient photocurrent response, electrochemical impedance spectra, and femtosecond transient absorption spectroscopy confirm the improved charge dynamics of Au–S v –CIS. In addition, temperature-programmed desorption of O 2 combined with density functional theory calculations conclusively demonstrates the superior O 2 adsorption capacity of Au–S v –CIS. This work provides a design strategy for efficient solar–to–chemical energy conversion through cooperative photocatalyst engineering.

The selective oxidation of 5-hydroxymethylfurfural (HMF) into 2,5-diformylfuran (DFF) is an important reaction for renewable biomass building blocks. Compared with thermal catalytic processes, photocatalytic production of DFF from HMF has attracted tremendous attention. Herein, the MoS 2 /CdIn 2 S 4 (MC) flower-like heterojunctions were prepared and considered as photocatalysts for selective oxidation of HMF into DFF under visible-light irradiation in aqueous solution. Results demonstrated MoS 2 in MC heterojunction could promote the separation of photoexcited electron-hole pairs, while the amount of MoS 2 dropping was proved influenced on the photocatalytic performance. 80.93% of DFF selectivity was realized when using 12.5% MC as photocatalyst. In addition, the MC catalyst also showed great potential in transformation of other biomass derived benzyl- and furyl-alcohols. The catalytic mechanism suggested that · O 2 - was the decisive active radical for HMF oxidation. Therefore, the MC heterojunction could be applied in photocatalytic conversion of biomass to valuable chemicals under ambient condition.

The remarkable pharmacological activities of flavonoids and their effects on human health have prompted many studies. To solve the problem that flavonoids are difficult to be accurately quantified, a novel photoelectrochemical (PEC) sensor based on CdIn 2 S 4 /b-TiO 2 /GO was created to detect the baicalein (BCA). By using physical ultrasonic compounding, a straightforward and effective CdIn 2 S 4 /b-TiO 2 /GO composite was created. The composite’s photoelectric effect was 14 times greater than that of the individual material. When BCA was present, a flavonoid-TiO 2 nanoconjugate was formed based on the interaction between b-TiO 2 and BCA. This interaction prevented the formation and decreased charge transfer of photoporous holes, resulting in a significant decline in photocurrent. Therefore, the PEC sensor based on the change of the electrode surface state can realize the sensitive detection of BCA. The PEC sensor has a wide linear detection range of 1 nM − 30 μM with a limit of detection of 0.5 nM. In addition, the sensor has exhibited excellent accuracy in detecting BCA in the roots and leaves of Scutellaria baicalensis, which can be used for the detection of actual samples.

The low activity of photocatalysts is mainly due to inefficient charge separation and low production of the active species. To overcome this challenge, we constructed an S-scheme CdIn 2 S 4 /MnZnFe 2 O 4 (CIS/MZFO) heterostructure, where the strong interface of the heterostructure leads to an upshift of the d-band center. CIS/MZFO shows higher charge transfer efficiency and oxygen adsorption/activation performance compared to CIS and MZFO separately, thereby increasing the production of ·O 2 − and h + active species. As a result, it demonstrats efficient photocatalytic degradation of tetracycline hydrochloride. The optimized CIS/MZFO heterostructure also shows good tolerance to various factors, such as inorganic ions, organic acids, pH and real water environments. The heterostructure also exhibits excellent magnetic recyclability and stability. Additionally, we propose a photocatalytic degradation pathway for tetracycline hydrochloride and evaluate the ecological toxicity that may arise from intermediates. This study provides an effective approach for the design of advanced photocatalysts.

In unbiased tandem cells, the production of C2+ products from CO2 reduction on the cathode is dependent on the effective supply of charge from the photoanode. At present, the development and understanding of efficient photoanodes remain challenging. A CoOOH nanosheet coupled CdIn2S4 film (CoOOH/CdIn2S4) was investigated as a photoanode to drive solar benzyl alcohol oxidation. Relative to the CdIn2S4 photoanode, lower carrier recombination, better activity and faster kinetics were achieved on the CoOOH/CdIn2S4 photoanode for benzyl alcohol oxidation to benzaldehyde. Several investigations jointly revealed that the oxidation of benzyl alcohol to benzaldehyde on the CoOOH/CdIn2S4 photoanode is mediated through the formation of hydroxyl radicals and the slight change of β-CoOOH into γ-CoOOH. Additionally, CoOOH coupling with CdIn2S4 is more energetically favourable for benzyl alcohol oxidation to benzaldehyde. Consequently, the CoOOH/CdIn2S4 photoanode shows high Faraday efficiency and selectivity for benzyl alcohol oxidation. In the CoOOH/CdIn2S4 photoanode–Cu2O cathode unbiased tandem cell, benzaldehyde and ethanol can be selectively produced from benzyl alcohol oxidation and CO2 reduction, respectively. Additionally, the CoOOH/CdIn2S4 photoanode can work stably to drive the unbiased cell, and 88% of its initial activity can be maintained after 4 h of reaction.

Photocatalytic H 2 O 2 production suffers from severe charge recombination and sacrificial agent dependency. Hydrangea-like Co-doped CdIn 2 S 4 superstructures (Co/CIS (HD)) synthesized via hydrothermal method exhibit hierarchical porous architecture that enhances light harvesting and reactant diffusion. Atomic Co doping introduces mixed-valence Co 2+ /Co 3+ species, reducing the work function from 6.287 to 5.896 eV and extending carrier lifetime. The dual-valent system establishes a self-regenerative redox cycle where Co 3+ mediates photogenerated electron transfer for O 2 activation while Co 2+ scavenges holes to suppress recombination and photocorrosion. Without sacrificial agents, the optimized 6.5-Co/CIS (HD) achieves an exceptional H 2 O 2 production rate of 1952 μmol g −1 h −1 under visible light, 6.33 times higher than pristine CdIn 2 S 4 . The catalyst maintains structural stability over five cycles due to dynamic Co 2+ /Co 3+ regeneration. This work provides a strategic design for efficient photocatalytic H 2 O 2 synthesis via synergistic morphological and electronic engineering.

In the realm of low-power gas sensing, bimetallic sulfides have garnered a lot of interest as prospective sensitive materials. However, their poor tolerance to dampness and delayed reaction kinetics makes them impractical. In order to modify the electronic structure of CdIn 2 S 4 and enhance its gas sensing capabilities, sulfur vacancies were added using atomic Cu doping. The test findings showed that Cu–CdIn 2 S 4 had a response value of 21 to 100 ppm triethylamine gas at a working temperature of 100 °C, which was five times greater than that of CdIn 2 S 4 . The minimal detection limit was 100 ppb. It also responds quickly and recovers quickly (2 s/33 s). Additionally, the sensor has good humidity resistance and selectivity. Cu doping into CdIn 2 S 4 increases the specific surface area and sulfur vacancy concentration, which speeds up the sensitive materials interaction kinetics with the target gas and improves gas sensing capability. The findings show that the defect design work has a lot of potential for use in low-power triethylamine detection, as it is an inexpensive and highly responsive gas-sensitive material.

H 2 /Ar etching created O/S vacancies at CWO/CIS interface, narrowing bandgap for full-spectrum absorption. • H 2 /Ar etching enhanced photothermal conversion via non-radiative recombination, channeling charge relaxation to heat. • CWO/CIS-H 2 Ar aerogel achieves 2.29 kg m −2 h −1 , 88.9% efficiency at 1 sun, outperforming single and unetched composites. • This evaporator shows excellent photothermal conversion and strong potential for wastewater treatment. Solar-driven interfacial evaporation represents a green technology for efficient photothermal conversion and wastewater treatment. In this work, we propose a novel dual-defect engineering strategy coupled with heterojunction construction to design a solar evaporator. Specifically, a CoWO 4 /CdIn 2 S 4 (CWO/CIS) heterojunction was first fabricated via a hydrothermal method, followed by controlled H₂/Ar etching at 600 °C for 3 h to simultaneously introduce oxygen and sulfur vacancies. The resulting defect-rich heterojunction was then integrated with sodium alginate to construct a three-dimensional porous aerogel evaporation system. H 2 /Ar etching introduced dual vacancies on the material surface, which synergistically narrowed the bandgap (from 2.02 eV to 1.90 eV) and broadened the full-spectrum light absorption range. More importantly, the etching process optimized the heterojunction interfacial contact by creating defect-mediated charge transfer channels, thereby significantly promoting photogenerated carrier separation and migration while suppressing electron-hole recombination, a key advantage over conventional heterojunction designs. These combined effects substantially enhanced the photothermal conversion efficiency. Under one sun irradiation, the optimized CWO/CIS-H 2 /Ar-aerogel achieved an evaporation rate of 2.29 kg m −2 h −1 in pure water with a corresponding photothermal conversion efficiency of 88.9%, substantially outperforming both the individual components and the non-etched composite. The evaporator demonstrated stable evaporation performance across diverse water matrices, including seawater, river water, heavy metal-ion wastewater, and tetracycline-contaminated water. Notably, it effectively removed heavy metal ions and organic pollutants such as tetracycline, rhodamine B (RhB), and methyl orange (MO). This work provides a novel defect-heterojunction synergistic strategy for developing high-performance solar-driven water evaporation systems, offering new insights into the rational design of photothermal materials with tailored electronic structures for water purification applications.

Inspired by natural photosynthesis, photocatalysis is considered a powerful means to address environmental pollution and the energy crisis. In this work, CdIn2S4 (CIS) nanosized octahedrons modified with sheet-like porous MoO2/MoP (MOP) as a non-noble metal cocatalyst were prepared by a simple hydrothermal method. In order to obtain the optimal MOP cocatalysts, the photocatalytic performance of the MOP/CIS composites was evaluated by H2 production and pollutant degradation under visible light irradiation. Among them, 7% MOP/CIS showed the best photocatalytic activity in H2 production (5.96 mmol·g–1·h–1), much higher than that of pure MOP and CIS. Additionally, it demonstrated excellent performance in the degradation of tetracycline (TC) and methyl orange (MO), with rate constants as high as 0.04911 min–1 and 0.03504 min–1, respectively. The superior photocatalytic performance of the MOP/CIS heterostructure was mostly attributed to the morphology design, broad visible light absorption, and effective separation of photogenerated charge carriers. This work provides a promising nanostructure design of visible-light-driven metal sulfide heterostructure for photocatalytic H2 production and pollutant degradation.

Photocatalysis, which represents a clean and efficient energy conversion technology, shows great potential for addressing both environmental pollution and the energy crisis. Within this context, photocatalytic CO 2 reduction and pollutant degradation represent important research directions. In this study, CdIn 2 S 4 /g-C 3 N 4 (g-C 3 N 4 , graphitic carbon nitride) composites were hydrothermally synthesized and assessed for their photocatalytic performance in the reduction of CO 2 and the degradation of methyl orange and tetracycline as model pollutants. Among the synthesized composites, the optimal photocatalytic activity was achieved by the CdIn 2 S 4 /g-C 3 N 4 (80) composite, with the degradation efficiency for methyl orange reaching 97.21% over 100 min and the reduction efficiency for CO 2 reaching 74.34 μmol g −1 over 4 h. The obtained results demonstrated that the heterojunction formed between CdIn 2 S 4 and g-C 3 N 4 effectively promoted the separation of photogenerated charge carriers while effectively suppressing their recombination, thereby improving the photocatalytic performance. Moreover, a cyclic stability experiment demonstrated that the CdIn 2 S 4 /g-C 3 N 4 composite exhibited excellent recyclability, which is important for its practical application. This work therefore provides a promising strategy for the design of highly efficient and stable photocatalysts toward sustainable environmental remediation and energy conversion.

In this study, CdIn 2 S 4 nanomaterials with tuneable morphologies were fabricated by applying a single-step hydrothermal method and were employed as anode materials for use in high-performance sodium-ion batteries. Compared to that of the microsphere sample, the hollow nanosphere architecture favoured an enhanced cycling performance because its void space efficiently mitigated volumetric expansion and reduced the transport distances for Na + and electrons, facilitating accelerated reaction kinetics. The hollow CdIn 2 S 4 nanosphere sample exhibited a high specific capacity and superior rate capability and an excellent cycling stability. This study demonstrates the structural advantages of the synthesised hollow architecture in terms of application as electrode materials.
