N, P-co-doped carbon coupled with CoP as superior electrocatalysts for hydrogen evolution reaction and overall water splitting

CoFeP/NC@CoP/Ni2P heterostructure for efficient overall water splitting

“…In addition, the peak at about 134.4 eV for the P-O bond is due to air exposure. 31,34 It is noteworthy that compared with CoFeP/NC and CoP/ Ni 2 P, the BEs of Fe Ni and Co species in CoFeP/NC@CoP/Ni 2 P show apparently positive shifts. Compared with CoFeP/NC, the BEs of P species in CoFeP/NC@CoP/Ni 2 P show negative shifts, but a positive shift compared with CoP/Ni 2 P, evidencing the partial charge transfer between the interfaces.…”

Defect Engineering of Oxygen Vacancies in Ultrathin NiFe-Layered Double Hydroxides: Insights from Density Functional Theory

“…Indeed, it is evident that defects significantly increase the interaction energy for all systems under study whereas trends concerning the magnitude of the binding energy with respect to the dopant heteroatom remain consistent. The results from this section align with empirical evidence regarding the remarkable performance of LDH composites with nitrogen-doped carbon for bifunctional catalysts. − Conversely, there has been rising interest in recent years regarding the utilization of carbon supports that incorporate sulfur (S) and phosphorus (P) dopants for electrocatalysis. ,,, Finally, Figure d presents maps of the charge density differences for NiFe LDH on the doped carbon materials. In all cases, it is evident that the interaction with the doped carbon leads to a redistribution of charge density in the LDH, primarily concentrated around the Fe metal cations.…”

In all cases, it is evident that the interaction with the doped carbon leads to a redistribution of charge density in the LDH, primarily concentrated around the Fe metal cations.…”

Solar H2 production systems: current status and prospective applications

“…The resulting system showed 12.3% η STH and good stability. 108 The work of Pan et al continued in the same field, thus emphasizing the [90][91][92][93][94][95][96][97][98][99][100][101][102][103][104] Complete information on data used in plot (b) is given in Tables S5 and S6 of the ESI. † need to improve the performances and the stability of low-cost and earth-abundant materials.…”
