WebSep 18, 2024 · Nanoparticle with a cupric oxide (CuO) surface as well as various cuprous oxide (Cu 2 O) cubes with different sizes is obtained and used for the CO 2 reduction reaction. It is observed that the Cu 2 O-derived electrodes show enhanced activity and carbon monoxide (CO) selectivity compared to the CuO-derived one. WebCuO + CO → Cu + CO 2 x mol x mol x mol x mol Áp dụng định luật bảo toàn khối lượng m hỗn hợp oxit + m CO = m chất rắn + m CO2 9,1 + 28x = 8,3 + 44x ⇒ x = 0,05 mol ⇒ m CuO = 0,05. 80 = 4 g Ví dụ 3: Khử 16 gam hỗn hợp các oxit kim loại: FeO, Fe 2 O 3, Fe 3 O 4, CuO và PbO bằng khí CO ở nhiệt độ cao, khối lượng chất rắn thu được là 11,2 gam.
