含有稀土的陶瓷材料钙钛矿型复合氧化物,在一定条件下,对特定的化学反应,具有催化活性。含烯土镧的四元复合氧化物 R_xB_(1-x)M)yT_(1-y)O_3,在80～90℃的较低温度和1大气压下,对 NO_x 和 CO 的氧化还原有催化作用。在微反应器中,通入模拟的大功率 CO_2激光器的工作气体,测定不同温度和不同空速下的氮氧化物转化率,结果表明这类氧化物可以作为实现 CO_2激光器工作气体在器腔内循环转化的催化剂,从而为延长激光器的连续工作时间创造了条件。
Containing rare earth ceramic material perovskite composite oxide, under certain conditions, for a specific chemical reaction, with catalytic activity. The ternary composite oxide R_xB_ (1-x) M) yT_ (1-y) O_3 containing alkene lanthanum has the catalytic effect on the redox of NO_x and CO at the lower temperature of 80 ~ 90 ℃ and 1 atm . In the microreactor, the working gas of the simulated high-power CO 2 laser was introduced into the reactor to measure the nitrogen oxides conversion under different temperatures and space velocities. The results show that these oxides can be used as the working gas for CO 2 laser in the cavity Circulating and transforming the catalyst, so as to extend the laser continuous working time to create the conditions.
