“…Exhilaratingly, it is proven that biomass products with a higher caloric value and higher stability can be obtained through a hydrogenation or hydrodeoxygenation process by using nanocatalysts or atomically dispersed catalysts. [5][6][7][8][9][10][11][12][13][14] As we know, single-atom catalysts (SACs) have uniform active centers with the highest atom utilization rate, and SACs are considered to be ideal catalysts for a lot of chemical reactions. [15][16][17][18][19][20][21][22][23][24][25][26] However, the effective synthesis and application of SACs are still a big problem, especially for metal atom carriers.…”
