The adsorption of poly （ethylene oxide）-b-poly（4-vinylpyridine）（PEO-b-P4VP） micelles onto the surface of yttrium hydroxide nanotubes （YNTs） resulted in the hybrid nanotubes with a dense P4VP inner layer and a stretched PEO outer layer surrounding YNTs. The dense P4VP layer was further stabilized by the crosslinking using 1,4-dibromobutane as the crosslinker. Then, the crosslinked hybrid nanotubes （CHNTs） were used as a novel nano supporter for loading the catalyst gold nanoparticles （GNPs） within the crosslinked P4VP layer. The resultant GNPs/CHNTs （GNTs loaded on CHNTs） were applied to catalyze the reduction reaction of p-nitrophenol. The results indicate that this novel nano supporter has advantages such as good dispersity in the suspension, high capacity in loading GNPs （0.87 mmol/g）, high catalytic activity of the loaded GNPs （12.9 μmol-lmin-i）, and good reusability of GNTs/CHNTs.

In the field of catalytic hydro-genation,two primary mecha-nistic pathways,namely the Ho-riuti-Polanyi(HP)mechanism and the non-HP mechanism,have been extensively *** understandings suggested that the non-HP mechanism preferred to occur on the coinage metal surfaces,such as copper,silver,and gold,which exhibited low activity towards H_(2) ***,we offered a detailed theoretical investigation into the mechanisms of CO_(2)hydrogenation to formic acid on M_(1)-In_(2)O_(3)(111)surfaces,using density functional theory *** calculations provided novel in-sights into the preference of the non-HP mechanism on reduced single-atom noble metal cata-lysts,such as r-Rh_(1)-In_(2)O_(3)(111)and r-Ir_(1)-In_(2)O_(3)(111).In these cases,molecularly adsorbed H_(2) would be polarized into H^(δ−)-H^(δ+),thus facilitating the electrophilic attack to the O in CO_(2).Conversely,the H^(δ+)species,derived from heterolytically dissociated H_(2),exhibited a strong affinity on the adjacent oxygen site at the M-O-In *** strong adsorption resulted in a higher energy barrier for CO_(2)hydrogenation,thereby rendering the HP mechanism less viable than the non-HP *** results were anticipated to provide a deeper understanding of hydrogenation reactions on oxide-supported noble single-atom catalysts and theoretical guidance for the development of novel high-performance catalysts for catalytic hydrogena-tion reactions.

The N-doped bismuth tungstate （BizWOt） photocatalysts with high visible light activity were prepared by the hydrothermal method using urea as a nitrogen source. The as-prepared N-doped Bi2WO6 samoles were characterized by X-ray diffraction, scanning electron microscopy, specific surface area, photocurrent analysis, and UV-Vis diffuse re- flectrance spectroscopy. The photocatalytic activity was evaluated by photocatalytic degradation of rhodamine B （RhB） solution under visible light irradiation. The photocatalytic mechanisms were analyzed by active species trapping experi- ments which revealed that the holes were the main active species of N-doped BizWO6 products in aqueous solution under visible light irradiation, rather than .OH and O-. With the assistance of H202, the photocatalytic activity for degradation of RhB could be further improved because H202 reacted with conduction band electrons to generate more hydroxyl radicals.

The BiOBr crystals doped with N and/or S have been prepared by a facile and rapid solvothermal method using urea and/or thiourea as doped resource. The morphologies and structures of the as-prepared samples were characterized by SEM, TEM, XRD, XPS and PL spectrum. Their electronic structures have been investigated and discussed using first principles based on the density functional theory. The photocatalytic properties of the products can be adjusted by the content and species of dopants.

The adsorption energy, electronic structure, density of states, and electron population for adsorption of HCHO on the hexagonal WO3 （h-WO3）（001） surfaces were investigated by density functional theory calculations. The adsorption energy of HCHO molecule on W and O sites of WO-terminated h-WO3 （001） surface was -0.309 and -0.432 eV compared with the value at -1.936 eV for HCHO molecule on O-terminated h-WO3 （001） surface. According to the calculated results, the adsorption of HCHO on h-WO3 （001） surface was spontaneous with physical adsorption on WO- terminated h-WO3 （001） surface and chemisorption on O-terminated h-WO3 （001） surface. The charge transfer from adsorbed HCHO molecule to WO3 （001） surface was confirmed by the Mulliken population analysis, which suggested the potential application of h-WO3 for HCHO gas detection.

Mesoporous materials have attracted increasing attention due to their wide application. In this paper, the Na4Ge9020 microspheres were firstly prepared by solvothermal method. Then, the as-prepared Na4Ge9020 microspheres were dispersed into Bi（NO3）3 solution, and the Bi4（GeO4）3 microspheres with mesoporous structure were formed due to the solid-state reaction between bismuth nitrate and Na4Ge9020. The morphology, structure and optical properties were characterized by SEM, EDS, XRD, FITR, BET and UV-Vis diffuse reflectance analysis. The as-prepared products exhibited excellent photocatalytic performance for degradation of reactive brilliant red X-3B under the UV light irradi- ation. A possible photocatalytic mechanism was discussed as well.
