Self-supported Ni/NiO heterostructures with a controlled reduction protocol for enhanced industrial alkaline hydrogen evolution.

Self-supported Ni/NiO heterostructures with controllable ratios used in industrial alkaline water electrolysis (AWE) systems lead to an ultralow voltage of 1.79 V at 400 mA cm for 2 weeks, ascribed to the synergic combination of abundant active sites, rapid electron/mass transfer and optimal HER kinetics.

Sulfidation-Induced Surface Local Electronic and Atomic Structures in a Silver Catalyst Enables Silicon Photocathode for Selective and Efficient Photoelectrochemical CO Reduction.

Converting CO to value-added chemicals through a photoelectrochemical (PEC) system is a creative approach toward renewable energy utilization and storage. However, the rational design of appropriate catalysts while being effectively integrated with semiconductor photoelectrodes remains a considerable challenge for achieving single-carbon products with high efficiency. Herein, we demonstrate a novel sulfidation-induced strategy for grown sulfide-derived Ag nanowires on a Si photocathode (denoted as SD-Ag/Si) based on the standard crystalline Si solar cells.

A bilateral employment situation prediction model for college students using GCN and LSTM.

Due to the prevailing trend of globalization, the competition for social employment has escalated significantly. Moreover, the job market has become exceedingly competitive for students, warranting immediate attention. In light of this, a novel prognostic model employing big data technology is proposed to facilitate a bilateral employment scenario for graduates, aiding college students in promptly gauging the prevailing social employment landscape and providing precise employment guidance.

Covalently Grafting Graphene onto Si Photocathode to Expedite Aqueous Photoelectrochemical CO Reduction.

Silicon semiconductor functionalized with molecular catalysts emerges as a promising cathode for photoelectrochemical (PEC) CO reduction reaction (CO RR). However, the limited kinetics and stabilities remains a major hurdle for the development of such composites. We herein report an assembling strategy of silicon photocathodes via chemically grafting a conductive graphene layer onto the surface of n -p Si followed by catalyst immobilization.
