Over the past several decades, extensive eforts have been undertaken to fnd methods to synthesize advanced electrocatalysts that possess rationally controllable sizes, shapes, crystallinities, compositions and structures for efcient energy conversion technologies. Of these methods, the one-pot seedless synthetic method in aqueous solution at ambient temperature has attracted extensive attention from researchers because it is a simple, inexpensive, energy-efcient, safe and less toxic method for the synthesis of electrocatalytic nanomaterials. In this review, recent developments in one-pot seedless synthetic strategies for the design of various structures of Au, Pt, Pd, Ag and multimetallic nanocrystals in aqueous solutions at ambient temperatures will be introduced, primarily focusing on the structure-electrocatalytic performance relationships of the as-prepared metal nanocrystals. Current challenges and outlooks for future research directions will also be provided in this promising research feld.
