Isolation of cobalt single atoms on hollow B, N co-doped defective carbon nanotubes for hydrogen peroxide production and tandem reagent-free electro-Fenton oxidation

Microdroplet assisted hollow ZnCdS@PDA nanocages’ synergistic confinement effect for promoting photocatalytic H2O2 production

“…S5 (ESI†) could be deconvoluted into two peaks corresponding to OC (531.6 eV) and O–C (532.7 eV), and the O–C bond is noteworthy because it suggests that PDA is bound to ZnCdS via an oxygen bridge, forming a Zn–O–C bond. 27,28 On the basis of the above-mentioned discussion, the successful preparation of the target products (ZnS, ZnCdS and ZnCdS@PDA) was initially demonstrated. In addition, comparing the S 2p peaks of ZnS, the positions of the peaks of both S 2p 3/2 (161.3eV) and S 2p 1/2 (162.5 eV) of ZnCdS (Fig.…”

Recent Advances in Carbon-Based Single-Atom Catalysts for Electrochemical Oxygen Reduction to Hydrogen Peroxide in Acidic Media

“…Furthermore, the possible site of the epoxy group in the second coordination sphere was also studied (Figure 4b). Yang et al proposed a nanotube reactor strategy via B, N-doped defective carbon nanotubes for the pursuit of high activity for the 2e − ORR in acidic conditions [56]. The Co-B,N-CNTs produced a high yield of 1508 mmol L −1 g cat −1 of H 2 O 2 with remarkable activity and selectivity via the 2e − ORR pathway in HClO 4 solution, ascribing to the Co-SACs with the uniformly dispersed and defect-rich active sites.…”

Multifunctional Ni-NPC Single-Atom Nanozyme for Removal and Smartphone-Assisted Visualization Monitoring of Carbamate Pesticides

“…Metal–nitrogen-doped carbon (M–N–C) materials, derived from metal–organic frameworks (MOFs), have garnered substantial attention as a class of sophisticated multifunctional materials with applications spanning diverse disciplines, including adsorption, sensing, drug delivery, gas storage, and heterogeneous catalysis, among others. − On one hand, M–N–C materials exhibited a high surface area and porous structure, enriched with nitrogen dopants within the carbon matrix, rendering them suitable for pesticide adsorption. On the other hand, the synergistic interplay between transition metals with nitrogen-doped carbon nanomaterials has shown the potential to enhance the catalytic activity of nanozyme .…”
