“…Under visible light irradiation, RhB concentration decreases by only 20% within 60 min without catalyst (curve III in Figure 7a), which is attributed to the degradation in the presence of visible light and H 2 O 2 [50]. H 2 O 2 is a kind of reactant to produce the active species (e.g., ·OH) under irradiation, and ·OH can accelerate the oxidation of organic compounds [51]. When photocatalyst is absent, the production of ·OH is not sustainable.…”

TS-1/C 3 N 4 composites were prepared by calcining the precursors with cooling crystallization method and were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), UV-Vis diffuse reflection spectrum (DRS) and nitrogen adsorption-desorption isotherm. The photocatalytic performance of TS-1/C 3 N 4 composites was investigated to degrade Rhodamine B (RhB) under visible light irradiation. The results showed that all composites exhibited better photocatalytic performance than pristine TS-1 and C 3 N 4 ; TS-1/C 3 N 4 -B composite (the measured mass ratio of TS-1 to C 3 N 4 is 1:4) had best performance, with a rate constant of 0.04166 min −1 , which is about two and ten times higher than those of C 3 N 4 and TS-1, respectively. We attributed the enhanced photocatalytic performance of TC-B to the optimized heterostructure formed by TS-1 and C 3 N 4 with proper proportion. From the results of photoluminescence spectra (PL) and the enhanced photocurrent, it is concluded that photogenerated electrons and holes were separated more effectively in TS-1/C 3 N 4 composites. The contribution of the three main active species for photocatalytic degradation followed a decreasing order of ·O 2 − , ·OH and h + . The degradation products of RhB were identified by liquid chromatography tandem mass spectrometry (LC-MS/MS), and the possible photocatalytic degradation pathways were proposed.

“…As already mentioned, its use has seen a dramatic decrease due to its impact on drinking water contamination. The United States environmental protection agency (USEPA) has in fact categorized MTBE as a possible carcinogenic agent, thus preventing its use as a gasoline additive since May 2006 [13]. Therefore, the USA, Canada, Japan, and Western Europe shifted to ETBE, ethanol, or TAME.…”

The use of solids acids in the synthesis of ethers suitable to be used as fuels or fuel additives were reviewed in a critical way. In particular, the role of Brønsted and Lewis acid sites was highlighted to focus on the pivotal role of the acidity nature on the product distribution. Particular emphasis is given to the recently proposed ethers prepared starting from furfural and 5-hydroxymethyl furfural. Thus, they are very promising products that can be derived from lignocellulosic biomass and bioalcohols and possess very interesting chemical and physical properties for their use in the diesel sector.

Cu and Ce co-doped ZnO powder has been carried out by sol-gel method in order to gain high performance photocatalyst. The structures, morphologies and photocatalytic properties of resultant (Zn 0.97-x Cu 0.03 Ce x O, x = 0.00, 0.02, 0.04, 0.06, 0.08, 0.10) have been investigated by XRD, SEM and the degradation rate of methyl orange. XRD analyses evidenced that the increase of Ce doping concentration will lead to the decrease of the crystal quality of Zn 0.97-x Cu 0.03 Ce x O powders. SEM indicated that the uniformity of particle size and the increase of the dispersion property of the doped sample will be beneficial to the suspension dispersion of the catalyst. At the same time, it can also promote the catalyst absorption of light and reactant molecules. Photocatalytic analysis showed the total degradation rate is close to one time function distribution with time, and the photocatalytic effect is obviously enhanced.
