Investigation into the relationship between surface structure and catalytic performance is pivotal for guiding the preparation of high-performance nanocatalysts. However, there is a lack of an effective strategy for fine-tuning the surface structure. In this paper, eight kinds of Au nanocubes (AuNCs) with structures ranging from concave to flat to convex were synthesized using trace amounts of Cu2+, and their surface structure-dependent catalytic performance was investigated. In the synthesis, H2O2 reduced Au3+ to Au+ in alkaline CTAB solutions first, and then ascorbic acid was added to initia...
