A metal–organic framework/polymer derived catalyst containing single-atom nickel species for electrocatalysis

Abstract

While metal-organic frameworks (MOF) alone offer a wide range of structural tunability, the formation of composites, through the introduction of other non-native species, like polymers, can further broaden their structure/property...

Metal–Organic Framework‐Based Electrocatalysts for CO2 Reduction

“…[215][216][217] Single metallic species performed as active sites for reducing CO 2 into valuable products, of course CO 2 RR performance is largely dependent on metal's locations, support, and preparation conditions (temperature, time, and preparation methodology). [218,219] The MOFbased synthesis is considered as an important strategy to isolate SACs, [39] for example, Co-, [206] Ni-, [96,164] Fe-, [101] and Cu- [159] based SACs. The first study to utilize SACs for electrochemical CO 2 reduction was reported by Li and coworkers [96] in which ZIF-derived N-doped carbon decorated with single Ni atoms (Ni SAs/N-C) was synthesized.…”

Metal–Support Interactions of Single-Atom Catalysts for Biomedical Applications

“…94,95 Specific functional groups can affect the coordination structure of single-atom metal sites in catalytic reactions. 96 Gao et al reported that the single Co atoms with a Co−N 4 moiety were uniformly anchored on a porous porphyrinic triazine-based framework (Co SAs/PTF) for the HER (Figure 4a). 97 Li et al proposed a new synthetic strategy for the in situ phosphatization of triphenylphosphine encapsulated within MOFs to design an atomic Co 1 −P 1 N 3 interfacial structure, where a cobalt single atom was stabilized by one P atom and three N atoms (denoted as Co-SA/P-in situ) (Figure 4b).…”

Tandem catalyzing the hydrodeoxygenation of 5-hydroxymethylfurfural over a Ni3Fe intermetallic supported Pt single-atom site catalyst

“…8,[13][14][15][16][17] Nevertheless, it is still challenging for one catalyst to simultaneously have high reaction kinetics for both the hydrogenation and dehydroxylation processes, and thus achieve high reaction efficiency and DMF selectivity without side-reactions (furan ring hydrogenation, ring opening, condensation reactions, etc.). [18][19][20] Recently, single-atom site catalysts (SACs) have been of major interest in heterogeneous catalysis with high atom utilization and enhanced catalytic performance, [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] which provide a great opportunity for efficient catalyst exploration towards the 5-HMF hydrodeoxygenation reaction. However, when applying SACs to catalyze the intricate tandem reactions needing multiple steps and catalytic sites, theoretically it is difficult for one single-atom site to cover all the catalytic steps with high efficiencies simultaneously.…”
