Photocatalytic materials for sustainable chemistry via cooperative photoredox catalysis

Semiconductor quantum dots: a versatile platform for photoredox organic transformation

“…Under mild reaction conditions, using exhaustless solar energy to drive selective photochemical reactions is an environmentally friendly route that can be potentially applied in various industrial organic transformation processes. [79][80][81] As one of the semiconductor photocatalysts, semiconductor QDs are widely used in photocatalysis such as CO 2 photoreduction, water splitting, degradation of organic pollutants, and organic redox reactions due to their inherent strengths in light absorption, exciton generation, and carrier transfer. 3,9,36,[82][83][84] In this context, the surface modication of QDs with different ligands 30,85 and/ or suitable cocatalysts 86,87 can effectively adjust the surface composition and charge distribution of catalysts, thus improving the performance of photocatalysts and improving the photocatalytic reaction efficiency.…”

Highly efficient photocatalytic formic acid decomposition to syngas under visible light using CdS nanorods integrated with crystalline W2N3 nanosheets

“…27,28 The byproduct of CO 2 can be hydrogenated to produce formic acid and can also be recycled by other methods to achieve a sustainable cycle of chemical energy. 18,29–31…”

“…27,28 The byproduct of CO 2 can be hydrogenated to produce formic acid and can also be recycled by other methods to achieve a sustainable cycle of chemical energy. 18,[29][30][31] Photocatalytic FA decomposition is also an efficient method to produce ratio-tunable syngas, usually using earth-abundant photocatalysts under sunlight irradiation. Therefore, the process is cost-effective and environmentally friendly and is better than thermal or electrocatalytic FA decomposition using precious-metal catalysts.…”

Improved photoelectrocatalytic performances over electrochemically reduced WO3: implications of oxygen vacancies

“…Since the Honda-Fujishima effect was proposed in 1972, the photoelectrocatalytic (PEC) water splitting hydrogen production technology based on nanostructured metal-oxide semiconductor photocatalysts has become a promising solution for the increasingly serious environmental pollution and the intensified energy crisis. [1][2][3][4] The efficiency of PEC technology is strongly dependent on the photoelectrode materials. It is worth noting that the use and design of suitable semiconductor materials as photoelectrodes is the key to improving PEC efficiency.…”
