The effects of TiO2 photocatalysis on the hydrolysis of protein of waste activated sludge (WAS) and its biodegradability were investigated in this study. After 12-h UV irradiation, the removal ratio of protein by TiO2 photocatalysis reached 98.1%. The optimal condition for photocatalytic degradation of protein is TiO2 dosage of 5.0 mg·L under 2.4 w·m UV light irradiation. TiO2 photocatalysis in...

Bisphenol A (BPA) is a well-known endocrine disruptor with adverse oestrogen-like effects eliciting adverse effects in humans and wildlife. For this reason it is necessary to set up an efficient removal of BPA from wastewaters, before they are discharged into surface waters. The aim of this study was to compare the efficiency of BPA removal from aqueous samples with photolytic, photocatalytic, ...

Photocatalytic coatings have potential as an air purifying technology for removal of pollutants such NOx gases, which are converted into and immobilized nitrate via photo-oxidation. This work is investigation the photocatalytic conversion nitrite in aqueous phase. The study this reaction important to understand mechanism through immobilization species nitrates takes place during conversion, esp...

BACKGROUND In order to perform selective CH functionalization upon visible light irradiation, Ru(II)-diimine functionalized P450 heme enzymes have been developed. The sL407C-1 enzyme containing the Ru(bpy)2PhenA (bpy=2,2'-bipyridine and PhenA=5-acetamido-1,10-phenanthroline) photosensitizer (1) covalently attached to the non-native single cysteine L407C of the P450BM3 heme domain mutant, displa...

Metal cocatalyst loading is one of the most widely explored strategies in promoting photocatalytic solar energy conversion. Engineering surface-active facets metal and exploring how t...

NOx can cause severe environmental problems such as acid rain and photochemical smog, endangering human health the living environment. Among them, NO pollution accounts for about 95%. exist stably in air a long time when concentration is lower than ppm level. Therefore, conversion of low has attracted more attention. However, traditional physical or chemical methods are difficult to deal with N...

The solar–to–chemical energy conversion of Earth-abundant resources like water or greenhouse gas pollutants CO 2 promises an alternate source that is clean, renewable, and environmentally friendly. eventual large-scale application such photo-based devices can be realized through the discovery novel photocatalytic materials are efficient, selective, robust. In past decade, Materials Genome Initi...

Here, Pd nanoparticles supported on ZnO were prepared by the alcohol-reduction and borohydride-reduction methods, their efficiency towards photocatalytic conversion of methane under mild conditions evaluated. The resulting Pd/ZnO photocatalysts characterized X-ray fluorescence, diffraction, photoelectron spectroscopy, UV–Vis, transmission electron microscopy. reactions performed with dispersed ...
