研究了以SiO2为载体的钯和钯-铊催化剂在葡萄糖氧化制葡萄糖酸反应中的催化性能。铊改性的催化剂比钯催化剂表现出更好的选择性和活性。XRD研究证明了金属间相互作用的存在，这可能增加了Pd-Tl/SiO2催化剂的选择性。特别注意的是，在催化反应过程中的铊和钯从催化剂的损失。
Catalytic properties of palladium and bimetallic palladium-thallium catalysts supported on SiO2 in the reaction of glucose oxidation to gluconic acid were studied. Catalysts modified with thallium showed better selectivity and activity than palladium catalysts. XRD studies proved the presence of intermetallic interactions, which probably increase the selectivity of Pd-Tl/SiO2 catalysts. Particular attention was paid to the losses of thallium and palladium from the catalysts during the catalytic reaction.
