fine-dispersed cage anchored AuNPs (Au@OC1R) have been finally used as potential heterogeneous photocatalyst for very facile and selective conversion of nitroarenes to respective azo compounds at ambient temperature in just 2 h reaction time. Exceptional chemical stability and reusability without any agglomeration of AuNPs even after several cycles of use are the potential features of this material. The composite
Atom-dispersed Au combined with nano-Au on halloysite nanotubes with <i>closo</i>-dodecaborate promotes synergistic effects for enhanced photocatalysis
Au single atoms (Au SAs) and Au nanoparticles (Au NPs) were obtained on HNT@B12H12@Au catalysts. Experimental and theoretical calculations revealed that O–Au–B–Au SAs, O–Au SAs, B–Au SAs and Au NPs are involved in the reaction simultaneously.
