Atom-dispersed Au combined with nano-Au on halloysite nanotubes with closo-dodecaborate promotes synergistic effects for enhanced photocatalysis

Abstract

The maximized metal dispersity provided by single-atom (SA) catalysts offers high catalytic activity, selectivity, and maximum metal utilization. However, the lack of adjacent metal atoms in these systems prevents further...

Applications of Boron cluster Supramolecular Frameworks as Metal-free Chemodynamic Therapy Agents

“…Notably, compared with the pure free radical signal of [B 12 H 12 ]-• (Figure S1) in our previous literature 32 , the [B 12 H 12 ]-• free radical signal of TPT@B 12 H 12 had a blue shift. Similarly, the free radical signal of [B 12 H 12 ]-• gradually enhanced and blue shifted when the irradiation time was prolonged.…”

“…The dodecahydro-closo-dodecaborate anion [closo-B 12 H 12 ] 2− is an icosahedron with a signi cant degree of symmetry, which has been the subject for various research studies such as supramolecular construction, 29 Boron neutron capture therapy 30 (BNCT), broadband membrane carriers 31 and in situ synthesis of nanomaterials. 32,33 Our group has been working on a series of nonmetallic materials, on supramolecular assemblies based on boron clusters with applications in optical, and on electrical and thermal catalysis. [34][35][36][37] Recently, supramolecular polymer-2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT)/[closo-B 12 H 12 ]2− (TPT@ B 12 H 12 ) was investigated as an e cient bifunctional carrier for the nano-goldcatalyzed selective reduction of nitrobenzene under visible light.…”

High Faraday efficiency of Cu1Co1–BCN based on a dodecahydro-closo-dodecaborate hybrid for electrocatalytic reduction of nitrate to ammonia

“…Na 2 [B 12 H 12 ] was prepared as per the methods outlined in the literature and our previous work. 45 First, 1 mmol of Cu(NO 3 ) 2 ·3H 2 O and Co(NO 3 ) 2 ·3H 2 O, 4 mmol of vinylimidazole, and 1 mmol of Na 2 [B 12 H 12 ] were combined in a 100 mL round-bottom flask with 40 mL of deionized water. This mixture was then condensed at 105 °C for 6 h. Thereafter, it was centrifuged twice, each time for 5 min, and the supernatant was removed.…”

Anti-Tumor Therapy through High ROS Performance induced by Ag Catalase from Boron Cluster with Halloysite Clay Nanotubes

“…39 This outstanding discovery would be a new starting point for the application of boron clusters and their derivatives in cell biology, neurobiology, and pharmacology research. Our group has been devoting considerable effort to developing boron clusters for application in supramolecular assembly, 40,41 optoelectronic nanomaterials, 42,43 and biological antibacterial 44 and photothermic therapies. 45 Recently, HNT-Au particles were designed for the selective photocatalytic reduction of nitrobenzenes.…”
