Abstract :In this study, the catalytic use of [Pdinsert ignore into journalissuearticles values(L1);2]Cl2 complex is aimed for the reduction / degradation reactions of organic pollutants in water sources which pose a threat to the environment. For this purpose, 2-insert ignore into journalissuearticles values(thiophen-2-yl);-1H-benzimidazole ligand insert ignore into journalissuearticles values(L1); and its Pdinsert ignore into journalissuearticles values(II); complex insert ignore into journalissuearticles values(C1); were synthesized and characterized by FT-IR, 1H-NMR, 13C-NMR, ESI-MS spectroscopic techniques. The catalytic efficiency of the C1 complex on the reduction of 4-nitro phenol compound insert ignore into journalissuearticles values(4-NP); and the degradation of rhodamine B insert ignore into journalissuearticles values(RhB);, methylene blue insert ignore into journalissuearticles values(MB); dyes was investigated in the presence of NaBH4 in aqueous medium. The catalytic performance was examined with single solutions of these substrates insert ignore into journalissuearticles values(4-NP and RhB, MB dyes); and at the end of 5 minutes, over 92% conversion was observed for all three substrates. In the catalytic trials with 4-NP + RhB + MB triple substrate mixture, 84, 94 and 93% conversion values were obtained, respectively, after 5 minutes. C1 complex catalyst is very effective in the simultaneous reduction / degradation of these toxic organic compounds from aqueous environments without any competition or selectivity.
