The design and fabrication of advanced nanocatalysts with the high activity, selectivity, and superior durability remains a big challenge in industrial catalysis [1,2]. The sintering of nanocatalysts under the thermally and/or chemically triggered conditions is a bottle-neck issue, which seriously decreases the amount of the exposed active sites and changes the original electronic structure of catalysts, resulting in the irreversible catalyst deactivation and high capital and time cost in industrial operation [3].
