Pt automatically adsorbed on oxygen vacancy of TiO via an in situ interfacial redox reaction, resulting in atomically dispersion of Pt on TiO. In the upgrading of lignin-derived 4-propylguaiacol, single-atom catalyst (SAC) Pt/TiO-H achieved a conversion of 96.9 % and a demethoxylation selectivity of 93.

Some important influence parameters such as concentrations of carrier, surfactant and stripping agent, agitation speed, extraction time, volume ratios of feed solution to emulsion phase and internal phase to membrane phase, and their effects on the removal efficiency of Tl in the ELM process were investigated and optimized. Under the optimum operating conditions of 2% of carrier, 5% of surfactant, 0.
