[Latest topic] TCTA019: Using activated carbon surface modification to remove low-concentration formaldehyde in indoor air

在本研究中，透過兩階段的方法改性活性碳。第一步是使用硝酸對活性碳表面進行預處理，使其含有氧官能團，以改變其孔結構和化學性質; 其次，添加金屬氧化物之奈米顆粒，以增加活性碳的表面積達到捕捉更多的甲醛或降解。在實驗中，選擇奈米銀和奈米銅顆粒披覆分散至活性碳中，能更有效率地去除低濃度甲醛。在實驗中，選擇奈米銀和奈米銅顆粒披覆分散至活性碳中，能更有效率地去除低濃度甲醛。
