The tubular microsphere structure is an effective structure for asymmetric supercapacitors due to its high specific surface area and porosity. It can slow down the volume shrinkage caused by redox process. In this paper, tubular-like NiMoO 4 ·xH 2 O microspheres were designed to reach a high specific capacity. The NiMoO 4 ·xH 2 O was prepared by hydrothermal method and subsequent annealing treatment showed a tubular microsphere structure with many particles uniformly distributed. And its specific capacity is 943 F g −1 at 1 A·g −1 and capacity retention is 73.4 % after 3000 cycles. The Bi 2 S 3 /C was selected as negative material to build an asymmetric supercapacitor (battery-type device). It exhibited an impressive specific capacity (419 F g −1 at 1 A g −1 ). It was worth noting that the battery-type devices built with NiMoO 4 ·xH 2 O and Bi 2 S 3 /C can achieve a specific energy of 27.1 Wh kg −1 at 2456.9 W kg −1 and capacity retention of 69.2 % after 5000 cycles. It was shown that NiMoO 4 -xH 2 O and Bi 2 S 3 /C as electrode materials have great potential and can enhance the energy storage application of supercapacitors.

Photothermal therapy (PTT) is limited by its shallow penetration depth, whereas high-dose radiotherapy (RT) can cause significant side-effects. To address these limitations, synergistic therapies integrating RT with PTT have been proposed and investigated as promising treatment strategies. In this study, multifunctional, magnetic-targeting nanoparticles that exhibit high near-infrared absorption and strong photon attenuation were successfully synthesized for the synergistic PTT-RT treatment of glioma. The platform consists of a Bi2S3 core encapsulated within a carbon shell. The nanoparticles were further doped with Fe3O4 to ensure arrival at the tumor site at an effective concentration to achieve optimal therapeutic outcomes, and to enable preferential aggregation at the intracranial tumor site under the guidance of an external magnetic field. The Bi2S3@C/Fe3O4 nanoparticles showed high biosafety and a significant synergistic therapeutic effect in combined RT and PTT, both in vitro and in vivo. The feasibility of Bi2S3@C/Fe3O4 nanoparticles for glioma treatment was systematically evaluated, providing evidence of the applicability of Bi-based nanomaterials in photothermal radiotherapy.

High theoretical capacity of Bi2S3 propels it toward an ideal anode material for lithium-ion batteries (LIBs); however, rapid capacity attenuation and poor long-term stability are major barriers to widespread application. In this work, an oxygen self-doping strategy was utilized to synthesize O–Bi2S3@C, significantly increasing the amount of active sites for lithium-ion storage. Meanwhile, sulfur vacancies were formed to improve the electrical conductivity and ionic transport efficiency, enhance the long-term stability, and accelerate the electrochemical kinetics of Bi2S3@C. O-BSC-S1:3 anode exhibits a reversible capacity of 673.1 mAh g–1 at 0.2 A g–1. It retains a long-term capacity of 596.3 mAh g–1 over 1100 cycles at a high density of 3 A g–1 in LIBs. Moreover, the installed O–Bi2S3@C//LiCoO2 full battery offers exceptional reversible capacity and remarkable cyclability (325.2 mAh g–1 after 200 cycles) at 0.2 A g–1. The combined strategy of oxygen self-doping and sulfur vacancy effectively enhances the reversible capacity and cycling life of Bi2S3, providing an approach for the design of high-performance transition metal sulfide anodes for LIBs.

Owing to its environmental compatibility and energy conservation properties, photocathodic protection (PCP) has emerged as a promising approach for metal corrosion protection. The key to efficient PCP lies in developing semiconductor composite materials that combine excellent photoelectrochemical performance with a simple preparation process. Herein, a carbon-doped TiO 2 /Bi 2 S 3 composite (Bi 2 S 3 /C-TiO 2 ) was fabricated via a single-step, low-temperature hydrolysis strategy using NH 2 -MIL-125(Ti) as the precursor, concurrently achieving carbon doping and incorporating a narrow-bandgap semiconductor. Characterization by UV-Vis diffuse reflectance spectroscopy and photoelectrochemical testing under illumination revealed that the composite exhibits significantly enhanced visible-light absorption while effectively suppressing photogenerated charge carrier recombination. Under optimized conditions, the Bi 2 S 3 /C-TiO 2 photoanode shifted the potential of coupled 304 stainless steel (304SS) to −464 mV (vs. Ag/AgCl) under visible-light irradiation—substantially below its corrosion potential—demonstrating effective photogenerated cathodic protection for 304SS.
