Insights into atomically dispersed reactive centers on g-C3N4 photocatalysts for water splitting

Revealing the charge transfer mechanism and assessing product toxicity in the 2D/1D Bi2O2CO3/Bi8(CrO4)O11 heterostructure system

“…Additionally, photoluminescence (PL) spectra and time-resolved transient PL spectra were applied to investigate the transfer of photogenerated charge carriers. 4,54,55 In Fig. 4c, 20% BOC/BCrO shows the lowest PL intensity compared with pure BCrO and BOC, further confirming that the recombination of photogenerated electron-hole pairs was suppressed after formation of the heterojunction.…”

Computational design of single-atom catalysts embedded on reduced graphitic carbon nitride monolayers

“…Following these two stability criteria, Au, Pd, Cu, Zn, Ni, Fe, and Co on the pg-C 3 N 4 substrate show both thermodynamic ( / E F c p < 0) and electrochemical ( / U diss c p > 0) stabilities, rendering these TM adatoms experimentally feasible for a variety of applications. It is encouraging to note that some of our predicted stable of SACs on g-C 3 N 4 (Co [22], Ni [56], Fe [57] Pd [58] and Au [59]) have been recently synthesized which confirms that the SACs predicted to possess high thermodynamic and electrochemical stabilities hold great potential for synthesis.…”

Synergistic Effects of Pyrrolic N/Pyridinic N on Ultrafast Microwave Synthesized Porous CoP/Ni2P to Boost Electrocatalytic Hydrogen Generation

“…Currently, the excessive consumption of fossil fuels is causing severe environmental problems. − Therefore, developing new clean energy alternatives to fossil fuels is a vital issue for the energy transition. Hydrogen is an ideal energy source due to its high energy density and no byproduct is generated during combustion. − Electrocatalytic water splitting, a new type of hydrogen production, owns significant advantages over other technologies because of the high-purity, the simplicity of the equipment, and the low cost of the raw materials. − However, the slow kinetics of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) reduce the water-splitting efficiency − and then electrocatalysts need to be developed to boost the reaction kinetics and thus reduce the charge of hydrogen energy. − Currently, Pt and RuO 2 /IrO 2 are considered as the most efficient catalysts for HER and OER, but the valuable price limits their commercial applications. − Therefore, the development of low-cost catalysts is the primary issue for hydrogen production from water splitting.…”
