Highly conductive NiSe2 nanoparticle as a co-catalyst over TiO2 for enhanced photocatalytic hydrogen production

Heterostructure Interface Construction of Cobalt/Nickel Diselenides Hybridized with sp2–sp3 Bonded Carbon to Boost Internal/External Sodium and Potassium Storage Dynamics

“…The existence of N element can be attributed to the pyrolysis of CN – in Co–Ni PBA. The two characteristic peaks at 873.3 and 855.9 eV in the Ni 2p spectrum (Figure e) correspond to the Ni 2p 1/2 and Ni 2p 3/2 orbitals, attributed to the +2 valence state of the nickel ion . For element Co, the two peaks at 782.2 and 797.7 eV in Figure f (Co 2p spectrum) originate from the Co 2p 3/2 and Co 2p 1/2 orbitals and can reasonably be inferred to the +2 valence state of the cobalt ion .…”

“…The two characteristic peaks at 873.3 and 855.9 eV in the Ni 2p spectrum (Figure 3e) correspond to the Ni 2p 1/2 and Ni 2p 3/2 orbitals, attributed to the +2 valence state of the nickel ion. 29 For element Co, the two peaks at 782.2 and 797.7 eV in Figure 3f reasonably be inferred to the +2 valence state of the cobalt ion. 30 The Se 3d spectrum is shown in Figure 3g, in which the characteristic peaks at 55.4 and 54.3 eV are attributed to the Se 3d 3/2 and Se 3d 5/2 orbitals, respectively, representing the Co−Se and Ni−Se chemical bonds.…”

Hydrogen evolution reaction of Ben + H2O (n = 5–9) based on density functional theory

“…Recent studies on two-dimensional structures, clusters and visible-light-driven photocatalytic hydrogen evolution reactions are also effective methods for developing hydrogen energy. 22–27 Vos et al . 28,29 reported a high level of single-reference and multi-reference ab initio calculations showing that Be 4 clusters exhibit very efficient Lewis acids when interacting with conventional Lewis bases such as ammonia, water, or hydrogen fluoride.…”

“…As doped, Be atoms effectively improve the NLO reaction, thermodynamics, and hydrogen adsorption properties of Al 12 N 12 nanoclusters, which were found in the study of Mehboob et al 21 Recent studies on two-dimensional structures, clusters and visible-light-driven photocatalytic hydrogen evolution reactions are also effective methods for developing hydrogen energy. [22][23][24][25][26][27] Vos et al 28,29 reported a high level of single-reference and multireference ab initio calculations showing that Be 4 clusters exhibit very efficient Lewis acids when interacting with conventional Lewis bases such as ammonia, water, or hydrogen fluoride. The corresponding acid-base interactions trigger the sequential dissociation of all Lewis bases.…”

Novel intramolecular-tailored g-C3N4 with accelerated charge delivery for photocatalytic tetracycline degradation and hydrogen production: experimental studies and theoretical analyses

“…1,2 Recently, several researchers have demonstrated that photocatalytic hydrogen production is one of the proven and effective methods. [3][4][5][6][7] Among masses of efficient semiconductor photocatalysts, graphite carbon nitride (g-C 3 N 4 ) holds unique advantages, such as extremely stable physical and chemical properties, various preparation methods, low cost, and nontoxicity, which is the basis for realizing the industrial application of photocatalytic technology. 8,9 However, g-C 3 N 4 still exhibits only unsatisfactory photocatalytic activity due to its insufficient visible light absorption and fast photogenerated carrier recombination.…”
