Abstract
Three-dimensional (3D) hollow nanosphere electrocatalysts that convert COinto formate with high current density and Faradaic efficiency (FE). The SnOnanospheres were constructed from small, interconnected SnOnanocrystals. The size of the constituent SnOnanocrystals was controlled between 2-10 nm by varying the calcination temperature and observed a clear correlation between nanocrystal size and formate production. In situ Raman and time-dependent X-ray diffraction measurements confirmed that SnOnanocrystals were reduced to metallic Sn and resisted microparticle agglomeration during COreduction. The nanosphere catalysts outperformed comparably sized, non-structured SnOnanoparticles and commercially-available SnOwith a heterogeneous size distribution.
