Rational design of novel Cu-containing catalysts for effective CO
2
conversion

T
he environmental pollution caused by massive carbon dioxide emissions has become one of the main obstacles to the national
health and economic development. It is now an urgent problem to develop novel CO
2
conversion catalysts. According to current
research, Cu electrode is reported to be the best CO
2
reduction catalyst among the commonly used metal electrodes. However, bulk
Cu electrode is also faced with a few problems like high overpotential, poor selectivity on products and low reaction efficiency due
to scaling relationships. In order to develop new Cu-based CO
2
reduction catalysts, we will focus on geometric optimization of low
dimensional nanomaterials and study their catalytic performances. The introduction of Cu atom, Cu2 dimer, Cu nanowires and
nano-flakes to one or two dimensional organic or inorganic systems may bring unique catalytic characteristic and break the limits of
bulk Cu electrode. These well-distributed Cu nanostructures are easier to controll and may show novel physical and chemical effects
including size effect, geometric effect, substrate effect, magnetic effect, curvature effect and spatial confinement effect, which may
improve CO
2
catalytic reduction.
