Significant enhancement of visible light photocatalytic activity of the hybrid B₁₂-PIL/rGO in the presence of Ru(bpy)₃²⁺for DDT dehalogenation

Abstract

A new hybrid catalyst, B12-PIL/rGO, was prepared. It exhibited enhanced photocatalytic activity for DDT dechlorination in the presence of Ru(bpy)32+.

Synergy of Bi2O3 and RuO2 Nanocatalysts for Low‐Overpotential and Wide pH‐Window Electrochemical Ammonia Synthesis

“…As a three-dimensional self-supporting carbon material with large surface area, high electron mobility and sufficient oxygen-containing groups (À OH, À COOH), FEG can be prepared by electrochemical exfoliating and oxidizing of graphite foil (GF), has been confirmed as a good candidate substrate for some electrocatalysts. [42,43] Therefore, we believe that the co-immobilization of RuO 2 and Bi 2 O 3 nanoparticles on the surface of FEG can effectively enhance the binding of N 2 molecules, inhibit the HER process, facilitate electron transport, and provide more active sites, and thus improving the electrocatalytic performance of NRR.…”

Bismuth-Based Free-Standing Electrodes for Ambient-Condition Ammonia Production in Neutral Media

“…The FEG modified by oxygen-containing groups (-OH, -COOH) that provide active defect sites, can act as an excellent substrate for metal oxides deposition when using the metal ions as the precursor [38]. It is the high surface area and excellent electron conductivity of graphene nanosheets that can accelerate the charge transport and keep credible electric contact, resulting in the enormously improved catalytic efficiency [39][40][41][42]. In addition, polymer binder (e.g., Nafion) is widely used for attaching the electrocatalysts to the collectors, which seriously hampers the mass transport and obstructs the charge transmission, and therefore reduces the overall catalytic performance of the electrocatalysts [43,44].…”

“…The aligand,5 ,6-dimethylbenzimidazole, is inherently connected to the corrin ring via af lexible linker.C onversely,arange of moieties, such as ÀCH 3 ,5 -deoxyadenosyl (Ado), H 2 O, and ÀCN, can serve as b-ligands, depending on the role of vitaminB 12 .T he environmentally benign nature of cobalamin inspires researchers to adopt it into various catalytic reactions, including deha-logenation of polychlorinated compounds, dimerization of benzylh alides, alkylation of olefins, cyclopropanation, cyclopropaner ing opening, or deprotection of (allyloxy)arenes. [4][5][6][7][8][9][10][11][12][13][14] All biological functions of vitaminB 12 ,a sw ell as its catalytic properties, involve oxidation or reduction of the central cobalt ion as the main feature. [15,16] The reduction potentials of Co III / Co II and Co II /Co I pairs mostlyd epend on the coordination state of the cobalt ion and on the natureo fa xial and equatorial ligands (trans and cis effect/influence).…”

“…Conversely, a range of moieties, such as −CH 3 , 5‐deoxyadenosyl (Ado), H 2 O, and −CN, can serve as β‐ligands, depending on the role of vitamin B 12 .
