Facile construction of a sulfur vacancy defect-decorated CoSx@In2S3 core/shell heterojunction for efficient visible-light-driven photocatalytic hydrogen evolution

“…2 Typically, the photocatalytic hydrogen-production process includes the following charge/mass-transport processes: the absorption of light, charge separation, charge transport to the catalyst surface, and bonding to H + to generate hydrogen. 3 In the past half a century, though various efforts have been tried to develop effective semiconductor-based hydrogen-harvesting photocatalysts, [4][5][6][7][8] unfortunately, the substantial recombination of photoexcited carriers and sluggish redox process are still limiting the hydrogen-evolution efficiency. 9 To resolve these drawbacks, guiding the rational construction of photocatalysts to establish an efficient pathway for charge separation and transport is essential.…”

Photothermal Effect- and Interfacial Chemical Bond-Modulated NiOx/Ta3N5 Heterojunction for Efficient CO2 Photoreduction

“…Along with semiconductor photocatalysis, the integration of multiple catalytic fields, specifically photothermal catalysis, offers a novel and promising approach to overcoming the thermodynamic and kinetic barriers associated with photocatalytic CO 2 reduction reactions . In photothermal catalysis, the catalytic system contains materials that are capable of self-heating through the photothermal effect, resulting in localized heating of the lattice and improved reaction kinetics, accelerated mass transfer, and enhanced migration of charge carriers in addition to the electron/hole engaged redox reactions upon light irradiation . Therefore, the use of photothermal catalysis has emerged as a burgeoning field that utilizes both the photochemical and thermal contributions of solar energy, making it a valuable addition to practical solar-to-chemical-energy conversion. , In order for this technology to be practically applied, the central issue is the design of the catalyst.…”
