Hydrogen production using an electrochemical cell might be alternative to conventional fuel systems (i.e., fossil fuels). The NiFe-layered hydroxide (NiFeOxHy) is one of the most popular electrocatalysts for water-splitting applications. However, its activity limited in hydrogen evolution reaction (HER) because minimal active sites and modest charge transfer rates. To overcome limitations NiFeOxHy, silver sulfide (Ag2S) graphitic carbon nitride (g-C3N4) were added as heterostructure cocatalysts. cocatalyst (Ag2S/g-C3N4) addition NiFeOxHy found improve double layer capacitance (EDLC) seven times greater than that pristine NiFeOxHy. sample enables with a minimum overpotential η10 = 43 mV Tafel slope 131 mV/dec saline water conditions. X-ray photoelectron spectroscopy reveals effectively donates electrons which enhance resultant ability electrocatalyst. In addition, density functional theoretical (DFT) analysis suggests exposed sulfur (S) within Ag2S/g-C3N4 serve prominent catalytic center H* interactions. This study highlights alteration dynamics via effective way facilitate enhanced alkaline reduction.

The construction of heterostructures promotes extending the light adsorption range graphitic carbon nitride (g-C3N4) materials, improving photogenerated charge carrier separation/transfer efficiency for attaining much enhanced performances. Because defective tungsten oxide (WOx) materials possess rich composition/morphology and an extended response in near-infrared region, WOx is a quite popular nanocomponent modifying g-C3N4, forming that can be used various photocatalytic applications involving water splitting, CO2 reduction, NOx removal, H2O2 generation, related chemical to fuel conversion reactions. In this review, important aspects WOx/g-C3N4 heterostructure photocatalysts are reviewed provide paradigms composition adjustment, structural design, these materials. growth control amorphous crystalline adjustment on types (e.g., type II Z-scheme), catalytic performances composite system also discussed detail. Moreover, effects synthetic methodologies preparation parameters formation two-dimensional layered inspiration state-of-the-art utilized photoredox challenges prospects future research summarized.
