摘要：

Four double atom catalysts (DACs) with controllable interatomic distances were achieved via solventless ball-milling, among which double-atom Ni-2/N-C showed good selectivity and superior catalytic activity to single-atom Ni-1/N-C for r-WGS reactions. The modular character of the synthesis provides a facile route to construct diverse atomic spacings of homo- and hetero-DACs.
