Controllable growth on nano-graphite-supported ZrO2–MnOx bimetallic oxides for electrocatalytic antibiotic degradation: mechanism to boost the Mn3+/Mn4+ redox cycle

“…42,43 The binding energies are lower than the values for ZrO 2 reported in the literature. 44 As illustrated in Fig. 4d, the deconvolution of the O 1s peaks corresponded to six components originating from Mn–O (approximately 529.06 eV) and Zr–O (approximately 529.36 eV), and at 530.45 eV there is physically adsorbed O, 45 O–C–O (approximately 531.67 eV), –CO (approximately 532.71 eV), 46 and –C–O– (approximately 533.61 eV).…”

Fabrication of High Surface Area Fe/Fe3O4 with Enhanced Performance for Electrocatalytic Nitrogen Reduction Reaction

“…Noble metals such as Au, [17–19] Pd, [20,21] and Ru, [22,23] have been demonstrated as efficient NRR catalysts in previous studies. For these catalysts, the scarcity and high price limit their large‐scale practical applications [24–27] .…”

“…[10][11][12][13] However, the extremely weak N 2 adsorption and the very strong bond energy of N � N demand efficient catalysts to adsorb and activate N 2 . [14][15][16] Noble metals such as Au, [17][18][19] Pd, [20,21] and Ru, [22,23] have been demonstrated as efficient NRR catalysts in previous studies. For these catalysts, the scarcity and high price limit their large-scale practical applications.…”

Enhanced N2 Adsorption and Activation by Combining Re Clusters and In Vacancies as Dual Sites for Efficient and Selective Electrochemical NH3 Synthesis

“…), nonprecious metals (Mo, Fe, Co, Mn, etc. ), and even nonmetals have been considered to be possible catalysts for converting N 2 to NH 3 . − However, an efficient electrochemical NRR largely depends on the catalysts with a suitable electronic structure. , Due to the lack of strong interaction between the occupied p-orbitals and the N 2p orbitals, these catalysts show poor selectivity. Recent researches have confirmed that p-block metal-based catalysts exhibit high NRR selectivity. − In addition to partially occupied orbitals, p-block metal-based materials can also be activated by the feedback of p-electrons, which occupies p-orbitals to return electrons to the unoccupied antibonding orbitals of N 2 , effectively weakening or even destroying the strong NN triple bond. − As a typical III–VI binary semiconductor p-block metal-based material, In 2 Se 3 has potential application in the NRR due to its various crystal structures. − The structural diversity and designability of In 2 Se 3 also provide the possibility for a highly efficient electrochemical NRR .…”
