一种分散在KIT-6二氧化硅（SiO2）纳米孔中的氧化铜（CuO）复合材料被用作检测低浓度硫化氢（H2S）气体的剂量计传感器。该传感器的原理是基于CuO到cu的可逆化学转化，保证了高选择性，并基于相应的渗透诱导的电子电导变化。
A composite material of copper oxide (CuO) dispersed in the nanopores of KIT-6 silica (SiO2) is used as a dosimetric sensor for the detection of hydrogen sulfide (H2S) gas in low parts per milion concentrations. The sensor principle is based on the reversible chemical conversion of CuO to CuS, which guarantees a high selectivity, and on the corresponding percolation-induced change in electronic conductance.
