In the present paper, nanosized TiO2 supported by zeolite was used in the ozonation of Songhua River as catalyst. The catalytic activity of TiO2/Zeolite for ozonation was testified by nitrobenzene removal, which is one kind of representatively resistant organic contaminant. And the removal of some organic and inorganic compounds existing in the Songhua River by TiO2/Zeolite catalyzed ozonation ...

A high-throughput screening (HTS) method based on fluorescence imaging (FI) was implemented to evaluate the catalytic performance of selenide-modified nano-TiO2. Chemical ink-jet printing (IJP) technology was reformed to fabricate a catalyst library comprising 1405 (Ni(a)Cu(b)Cd(c)Ce(d)In(e)Y(f))Se(x)/TiO2 (M6Se/Ti) composite photocatalysts. Nineteen M6Se/Tis were screened out from the 1405 can...

PtIr/TiO2 catalyst was prepared and investigated for the selective catalytic reduction of NOx by H2 (H2-SCR) in presence O2. It found that exhibited higher H2-SCR activity as well wider temperature window than Pt/TiO2 Ir/TiO2 catalysts, optimum mass ratio Pt/Ir 1:1. Characterization showed metallic Pt Ir were generated on PtIr/TiO2, both which favorable active sites process. In situ DRIFTS stud...

The regulation of the interaction between H2O2 and its catalysts is a promising route to achieve high productivity and selectivity towards H2O2. Herein, mesoporous anatase/TiO2(B) whisker (mb-TiO2) modified with heterogeneous carbon was prepared as the support of Pd-based catalysts for the direct synthesis of H2O2. The morphology and structure of the catalyst were investigated by transmission e...

Oxidative coupling of methane (OCM) is a promising method for the direct conversion of methane to ethene and ethane (C2 products). Among the catalysts reported previously, Mn2O3-Na2WO4/SiO2 showed the highest conversion and selectivity, but only at 800° to 900°C, which represents a substantial challenge for commercialization. We report a TiO2-doped Mn2O3-Na2WO4/SiO2 catalyst by using Ti-MWW zeo...

An efficient, simple and convenient route is described for the synthesis of biscoumarin (3,3'-(arylmethylene) bis (4-hydroxy-2H-chromen-2-one)) by using of recyclable catalyst TiO2@KSF. In this Method, we synthesis biscoumarin derivatives via 3multi-component reactions (3MCRs) of two equivalent 4-hydroxycoumarin with one equivalent of aromatic aldehydes using 20 mg nano TiO2@KSF as homogeneous ...

An efficient, visible light active, N, S-codoped TiO2-based photocatalyst was prepared by reacting thiourea with nanoparticulate anatase TiO2. Commercial anatase powders were manually ground with thiourea and annealed at 400 °C in two crucibles with different surface-to-volume ratios (S/V ) 20 and 1.5) to prepare two N, S-codoped TiO2 materials. The differentiated aeration conditions during the...

The immobilisation of molecular catalysts on semiconductors for solar fuel production is an attractive strategy to exploit electrocatalysts in a heterogeneous photocatalytic environment. Efficient H2 production in such hybrid systems requires effective electronic coupling between the light harvesting unit and the electrocatalyst. Current examples based on non-precious metal complexes include Co...

Water pollution by organic pollutants has been a growing global problem in recent years, for which there is a great demand of efficient technologies for wastewater treatment. Remediation of water by photocatalytic oxidation has several advantages over adsorption or any other conventional techniques. This study reports a easy synthesis technique of a sulfur doped hollow TiO2 nanocatalyst for pho...
