Photocatalytic hydrogen evolution from water has triggered an intensive search for metal-free semiconducting photocatalysts. However, traditional materials suffer limited efficiency owing to low intrinsic electron transfer, rapid recombination of photogenerated carriers, and lack artificial microstructure. Herein, we report a half-metallic carbon nitride highly efficient photocatalytic evolution. The introduced features not only effectively facilitate carrier transfer but also provide more...

Abstract The exploitation of the stable and earth-abundant electrocatalyst with high catalytic activity remains a significant challenge for hydrogen evolution reaction. Being different from complex nanostructuring, this work focuses on simple feasible way to improve reaction performance via manipulation intrinsic physical properties material. Herein, we present an interesting semiconductor-metal transition in ultrathin troilite FeS nanosheets triggered by near infrared radiation at room...

The future of sustainable fertilizers and carbon-free energy carrier demands innovative breakthroughs in the exploitation efficient electrocatalysts for synthesizing ammonia (NH3) from nitrogen (N2) mild conditions. Understanding regulating reaction intermediates that form on catalyst surface through careful design could bypass certain limitations associated with ambiguous adsorbate evolution mechanism. Herein, we propose ternary intermetallic Re2MnS6 ultrathin nanosheets include orderly...

Black phosphorus nanoparticles (BP NPs) possess great advantages in photocatalysis owing to the rich surface active sites, extremely high carrier mobility, and strong visible–near-infrared light response. However, complex preparation process, poor stability, rapid recombination restrict their successful application photocatalysis. Herein, above problems are resolved by preparing BP NPs through a facile sonication-assisted hydrothermal method. To further improve stability photocatalytic...

In this paper, the optical trapping of multiple particles based on a rotationally-symmetric power-exponent-phase vortex beam (RSPEPVB) was introduced and demonstrated. Based theories tight focusing force, force model RSPEPVB established to analyze tightly focused RSPEPVB. Then, an experimental setup tweezer, by utilizing RSPEPVB, built demonstrate that tweezer RSPEPVBs can achieve particles, number captured is equal topological charge l which shows multi-particles with controllable number....

In this paper, the generation and propagation properties of Bessel–Gaussian (BG) rotationally symmetric power-exponent-phase vortex beam (RSPEPVBs) were demonstrated discussed. The results showed that BG-RSPEPVBs can be directly generated based on spatial light modulator, which phase singularities verified by interference patterns with plane wave. It found intensity distributions BG-RSPEPVBs, different topological charges (TCs) power orders, fan-shaped polycyclic, possessed characteristics...
