Rational construction of 3D MoNi/NiMoOx@NiFe LDH with rapid electron transfer for efficient overall water splitting

Stable Seawater Oxidation at High-Salinity Conditions Promoted by Low Iron-Doped Non-Noble-Metal Electrocatalysts

“…35 Two peaks are observed at 529.5 and 530.6 eV (Figure 3d) for the O 1s spectrum of the Fe−NiO x H y /CC catalyst, with the former corresponding to the binding energy of M−O and the latter corresponding to M−OH. 47,48 This suggests that the sample is in a mixed state of NiOOH, FeOOH, and Ni(OH) 2 , 49 which are unstable during the reaction due to mutual transformation. 43 The XPS measurement on S 2p suggests that there is no S in the sample after oxidation (Figure S4, Supporting Information).…”

Tunable d-band center of a NiFeMo alloy with enlarged lattice strain enhancing the intrinsic catalytic activity for overall water-splitting

“…S10 †), which demonstrated that NiFeMo/SSM showed a high level of HER performances and relatively satisfactory catalytic kinetics among the Ni-based catalysts. In addition, to accurately investigate the characteristics of electrode kinetics and interfacial reactions, 18 the ECSA of the electrodes is tested. The ECSA can be estimated from the electrochemical double-layer capacitance, 35 which can be calculated by CV at different scan rates.…”

“…Bimetallic and trimetallic composites have attracted much attention recently for their excellent performance, durability, and low cost. [16][17][18][19][20] Alloy-type transition metal catalysts (e.g. NiFe) are considered to be one of the most promising candidates due to their better catalytic performance than that of a single metal, and can cooperatively modify the electronic structure and lower the energy barrier.…”

Recent developments and future perspectives on energy storage and conversion applications of nickel molybdates

“…This is so because this strategy offers the most convenient processes and yet conducive outcomes. Table 6 is to impart a brief account of a host of developments in catalytic properties of NiMoO 4 done involving heterostructures and hybrids 121,123,256‐382 . in many cases, doping, defect and/or morphology engineering have been amalgamated with the heterostructure for superior enhancement in catalytic properties either to generate more surface area or more population of active sites or for other special necessities as summarized in Table 6.…”
