| Abstract |
Improving catalytic performance of syngas conversion to form C2 oxygenates on the Cu-based catalyst is still a challenge. Here, 2D h-BN material covered Cu confined catalysts (xh-BN/Cu) with different spatial dimensions are rationally designed to unravel the function of spatial dimension in tuning the activity and selectivity of C2 oxygenates. The results show that the spatial dimension caused by h-BN coating in the h-BN/Cu catalyst can alter the dominant existence form of CHx(x=1-3) monomer and the corresponding activity and selectivity, in which the confinement effect arisen from h-BN coating with different spatial dimensions is confirmed to be the determined factor instead of the electronic effect. The screened 4.0h-BN/Cu catalyst has outstanding catalytic performance toward the production of dominant CHx(x=1-3) monomer and C2 oxygenates. The finding provides the new design principle to rationally construct 2D material covered metal confined catalysts by adjusting the confined spatial dimension to improve catalytic performance. |
