Red phosphorus (RP) has attracted wide attention as a promising anode candidate for sodium ion batteries due to its admirable specific capacity, safe working potential and low cost. However, its large volumetric expansion during desodiation/sodiation process and poor electronic conductivity hinder the progress of red phosphorus electrodes. Here, the N -enriched reduced graphene oxide-C 3 N 4 (rGO-C 3 N 4 ) network is utilized to facilitate the electronic conductivity and construct a robust architecture through P N bonds. Admirable bonding strength between phosphorus and the C 3 N 4 hybrid framework is revealed by the calculations via the first principles based on density function theory. The red phosphorus/rGO-C 3 N 4 anode for sodium ion batteries obtained via a facile ball-milling method exhibits a discharge capacity of 652.6 mA h g −1 after 100 cycles. This method holds great promise on developing red phosphorus anode on sodium-ion batteries.

TiO 2 /g-C 3 N 4 (TCN) thin film electrode was fabricated via a surface hybridization and dip-coating method. Phenol could be completely mineralized and the pollutants in coking wastewater could be degraded quickly by TCN under simulated solar light and electric field. The characteristics of the photoelectrocatalytic (PEC) degradation of phenol-containing coking wastewater were investigated under visible light, ultraviolet light and simulated solar irradiation. The results showed that phenol was degraded completely by the TCN-0.3 with a 1.5 V bias in 1.5 h under simulated solar irradiation with 100% TOC removal rate. 45% of the TOC for the coking wastewater was removed by the TCN-0.3 with a 1.5 V bias under 5.0 h simulated solar irradiation, which was 2.45 and 5.69 times as high as that of the pure TiO 2 and g-C 3 N 4 , respectively. The surface hybrid heterojunction formed between TiO 2 and g-C 3 N 4 promotes the migration of the photogenerated electrons and holes and greatly improves the degradation efficiency with applied potential. The significant synergistic effect between the electrocatalytic and photocatalytic oxidation processes in PEC is conducive to electron-hole pair separation, producing the more active substances, such as hydroxyl radicals, and increases the degree of degradation and mineralization of phenolic compounds.

Hierarchical porous g-C 3 N 4 nanosheets are prepared from melamine using NH 4 Cl as dynamic gas templates to anchor the ultrafine Ru nanoparticles (NPs) with a facile adsorption -in situ reduction strategy. The results reveal that 1: 3 is the optimal mass ratio for melamine to NH 4 Cl and the Ru NPs are evenly dispersed in the porous network of g-C 3 N 4 in the corresponding catalysts. Remarkably, the porous catalysts exhibit superior catalytic activity and satisfactory recyclability for ammonia borane (NH 3 -BH 3 , AB) hydrolysis. The corresponding turnover frequency is as high as 122.2 × 10 3 mL H 2 · g Ru -1 · min -1 and the apparent activation energy (35.6 kJ mol −1 ) is competitive. AB hydrolysis is of 1.17-order and near zero-order with respect to the Ru and AB concentrations, respectively. The results demonstrate that the Ru/g-C 3 N 4 catalysts are promising in developing an alternative clean and environmentally friendly energy carrier from the hydrogen storage materials.

In this study, a g-C 3 N 4 /MoS 2 composite membrane was successfully fabricated via electrostatic interactions and vacuum-assisted self-assembly. The established heterojunction markedly enhanced charge separation, yielding superior visible-light photocatalytic activity with 95.5% methylene blue degradation in 150 min. The membrane also demonstrated efficient dye separation (70.8% rejection for carmine red; 66.7% for malachite green) and notable antifouling properties, achieving a 74.9% flux recovery after visible-light cleaning. This work presents a synergistic strategy for simultaneous photocatalytic degradation and membrane separation in advanced water treatment.

Carbon nitride is an intriguing visible-light photocatalyst for H 2 production but suffers from low surface area and fast charge recombination. Here, we report a simple yet efficient approach to fine tune the porous structure, modify the electronic structure and carrier behaviors of C 3 N 4 through in-situ growth of MnO x by NaCl template-assisted strategy. This NaCl template method simultaneously constructs 3D porous structure for high surface area, induces Na coordination with N atoms and accompanying cyano group to form an internal donor-acceptor system for efficient charge transfer and separation. Along with the MnO x growth, the band gap of C 3 N 4 is narrowed for stronger visible light absorption and the conduction band level is negatively shifted for stronger reduction capability. Thus, the resulted C 3 N 4 (MSCN) shows much improved activity of about 18 times higher than bulk C 3 N 4 in photocatalytic hydrogen evolution reaction under visible light irradiation.

Developing effective catalysts for hydrogen evolution from hydrolysis of ammonia borane (AB) is of great significance considering the useful applications of hydrogen. Herein, graphitic carbon nitride (g-C 3 N 4 ) prepared through the simply pyrolysis of urea was employed as a support for Rh nanoparticles (NPs) stabilization. The in-situ generated Rh NPs supported on g-C 3 N 4 with an average size of 3.1 nm were investigated as catalysts for hydrogen generation from the hydrolysis of AB under mild conditions. The Rh/g-C 3 N 4 catalyst exhibits a high turnover frequency of 969 mol H 2 · (min·mol Rh ) −1 and a low activation energy of 24.2 kJ/mol. The results of the kinetic studies show that the catalytic hydrolysis of AB over the Rh/g-C 3 N 4 catalyst is a zero-order reaction with the AB concentration and a first-order reaction with the Rh concentration. This work demonstrates that g-C 3 N 4 is a useful support to design and synthesis of effective Rh-based catalyst for hydrogen-based applications.

Herein, NiO cubes with {100} facets or NiO trapezohedrons with {311} facets modified graphite carbon nitride (g-C3N4) nanoparticles acidified by HCl (HCN) were fabricated to form a p-n heterojunction (NiO/HCN) for the first time. These were further used for the degradation of rhodamine B (RhB) in water. 8-{100}NiO/HCN exhibited the highest degradation efficiency of 98.56% in just 60 min within peroxymonosulfate (PMS) under visible light. It was 2.51% higher than that of 8-{311} NiO/HCN. A series of characterization and experimental results showed that introducing {100} NiO could improve both the photocatalysis and PMS activation efficiency of the g-C3N4 compared with {311} NiO. The influence of environmental parameters on RhB degradation was systematically studied as well. Stability experiments demonstrated that 8-{100}NiO/HCN maintained high catalytic performance over a period of 10 h. The degradation mechanism behind PMS activation under visible light involved several factors: the unique micron-nano interface structure, electron (e-) transfer between NiO and g-C3N4, as well as effective facilitation of PMS activation by Ni2+. These factors led to the formation of singlet oxygen (1O2), which contributed significantly to RhB degradation. Overall, this work highlights how facet design can be utilized in metal oxide cocatalysts to improve photocatalytic degradation performance.

This dual-site strategy offers a new route for steering CO 2 reduction and catalyst design. • Synergistic dual sites boost charge transfer, CO 2 adsorption, and *OCH 3 formation. • Cobalt-based porphyrin (CoTCPP) sites on graphitic carbon nitride accounts for CO 2 reduction into CH 4 . • Ag/CoTCPP dual sites achieve 340-fold higher than graphitic carbon nitride photocatalyst for CO production. Graphitic carbon nitride (g-C 3 N 4 ) was identified as a highly promising catalyst for the photocatalytic reduction of CO 2 . However, its performance was limited by a lack of highly efficient active sites for photogenerated electron accumulation and CO 2 adsorption/activation. In this study, a cobalt porphyrin (CoTCPP) and Ag dual-active-site co-modified CNN (CoTCPP/Ag/CNN) was prepared for boosting photocatalytic CO 2 reduction. When the Ag loading was 1 wt% and the CoTCPP loading was 0.5 wt%, the catalyst exhibited optimal activity, with CO and CH 4 yields reaching 67.8 μmol g −1 ·h −1 and 10.4 μmol·g −1 ·h −1 , respectively, whereas pure CNN produced only 0.2 μmol·g −1 ·h −1 of CO. The experimental results indicated that the dual-type sites not only effectively enhanced the photo-generated carrier mobility, but also significantly strengthened the CO 2 adsorption and activation, and promoted the formation of the key intermediate *OCH 3 , thereby markedly improving the efficiency of CO 2 photoreduction. This study proposed a novel strategy for the rational design of dual active sites on catalyst surfaces and the regulation of CO 2 reduction reaction pathways.

Thyroid-associated ophthalmopathy (TAO) is a complex autoimmune inflammatory disease. There is an urgent clinical need for highly sensitive and minimally invasive biomarkers to enable early diagnosis and dynamic disease monitoring. Among them, miR-320a has been confirmed to be closely associated with oxidative stress regulation, fibroblast activation, and fibrosis progression. However, current detection methods, especially those based on real-time quantitative polymerase chain reaction (RT-qPCR), still suffer from cumbersome procedures, high instrumentation costs, and limited adaptability for rapid point-of-care diagnostics. To address this, we developed a nanozyme-assisted colorimetric biosensing platform integrating target-triggered probe hybridization with Co-g-C 3 N 4 , which exhibits enhanced peroxidase-like activity and stability. The method involves Co-g-C 3 N 4 synthesis, probe-nanozyme interface construction, catalytic optimization, and colorimetric detection via TMB oxidation, validated in spiked serum and with smartphone readout. The platform achieves sensitive miR-320a detection down to picomole levels with excellent linearity and specificity. In spiked human serum analysis, it reliably quantifies endogenous miR-320a with strong recovery rates (94.6-108.9%). However, we acknowledge that direct clinical validation using confirmed TAO patient samples is required for full diagnostic implementation, and this represents a limitation of the current study. Generally speaking, this work provides a portable, cost-effective, amplification-free colorimetric nanozyme platform for miRNA detection, requiring only basic laboratory equipment, and holding significant promise for point-of-care precision diagnostics in autoimmune and fibrotic diseases.

A rough burr tubular structure APCN-30 were synthesized by a simple thermal copolymerisation method. • The obtained APCN-30/PMS/Vis showed promoted degradation of TC, along with increased photogenerated charge separation ability. • Mechanism on TC degradation system employed APCN-30/PMS/Vis is elucidated. The presence of residual antibiotics in water sources poses a major threat to human health and ecosystems. Effective degradation methods are needed to treat tetracycline residues in aquatic environments to reduce their negative effects on the environment and ecosystems. Diazole ring (AP)-doped g-C 3 N 4 (APCN-X) was synthesized via thermal polymerisation. Peroxymonosulfate-assisted(PMS) photocatalytic tetracycline degradation system based on APCN-X under visible light was constructed. Results showed that the photocatalytic degradation rate of Tetracycline(TC) by the APCN-30/PMS/Vis system was 91.84%/100min (compared to 69.35% for g-C 3 N 4 (CN)/PMS/Vis), which was 5.24 times higher than that of CN/PMS/Vis. The possible mechanism of APCN-30 enhanced the photocatalytic activity of PMS was discussed. Download: Download high-res image (378KB) Download: Download full-size image

The narrow light-absorption range and fast charge carrier recombination in semiconductor photocatalysts remain major bottlenecks limiting photocatalytic hydrogen evolution efficiency. In this work, SnO 2 /g-C 3 N 4 /TiO 2 ternary Type-II heterojunctions were rationally constructed via a hydrothermal-calcination two step strategy. Triethanolamine (TEOA) was employed as a sacrificial agent during the photocatalytic hydrogen production reaction. Different from traditional simple component mixing, SnO 2 is deliberately designed as an electron mediator to bridge g-C 3 N 4 and TiO 2 , forming a directional cascade charge transfer channel for efficient carrier separation. DFT theoretical simulations further verify that the introduction of TiO 2 optimizes the band structure, reduces the work function, and promotes interfacial electron transfer, thus significantly enhancing photocatalytic performance. The optimized 0.20SnO 2 /g-C 3 N 4 /TiO 2 sample delivers a maximum H 2 evolution rate of 4.80 mmol/g/h, 2.38-fold higher than that of bare TiO 2 . Stability assessments confirmed the material's exceptional cycling durability, a characteristic primarily ascribed to the establishment of type II heterojunctions. This architectural configuration facilitates effective segregation and mobility of photoinduced charge carriers while simultaneously suppressing recombination of electron-hole pairs. The materials' superior photoelectrochemical characteristics further enhance their capacity for light-driven hydrogen generation through catalytic processes. These discoveries provide new perspectives and innovative approaches for engineering high-performance photocatalytic systems.

With the advancement of the pharmaceutical industry and livestock farming, the increasing release of antibiotic-containing wastewater poses serious threats to both the natural environment and human health. Developing novel, efficient technologies to remove tetracycline from water is a critical priority. In this study, a ternary BiOBr/g-C 3 N 4 /EG composite was successfully synthesized via a one-step solvothermal method. Under optimal conditions, the composite achieved a tetracycline (TC) removal efficiency of 98.49% within 50 min of visible-light irradiation, with degradation rate constants 1.40 and 1.74 times higher than those of pristine BiOBr and g-C 3 N 4 , respectively. XPS analysis revealed that the introduction of EG effectively suppressed the photoreduction of Bi 3+ to metallic Bi 0 , confirming that EG acts as an electron trap and establishes strong interfacial electronic interactions. BET analysis showed that the ternary composite possesses a specific surface area of 60.0 m 2 /g, which is significantly larger than that of BiOBr (28.9 m 2 /g) and g-C 3 N 4 (37.1 m 2 /g), promoting active site exposure and pollutant adsorption. PL spectroscopy demonstrated a marked decrease in emission intensity for the ternary composite, indicating effective suppression of electron–hole recombination. Mechanistic studies, including radical trapping and EPR, identified ·O 2 − and h + as the primary reactive species governing TC degradation. The enhanced performance is attributed to the synergistic effects of EG: (i) its oxygen-containing functional groups anchor BiOBr and g-C 3 N 4 , preserving heterojunction integrity; (ii) it serves as an electron trap to accelerate charge separation; and (iii) it enlarges the specific surface area and provides a conductive network for rapid charge transfer. This work offers a feasible and innovative strategy for designing high-performance carbon-supported semiconductor heterojunctions for environmental remediation.
