“…In a previous paper we demonstrated that deposition of Pt metals onto TiO 2 only slightly influenced the absorption spectra of C 2 H 6 at the room temperature [15]. In the case of Au/TiO 2 the adsorption of H 2 O + C 2 H 6 produced absorption bands at 3001, 2963, 2952, 2928, 2890, 2870 and 1636 cm −1 , which agreed well with those obtained for pure TiO 2 [15].…”

“…20 The conversion of C 2 H 6 was low on TiO 2 (~4% at 300 K). However, the photo-induced decomposition of C 2 H 6 could be greatly improved by doping TiO 2 with noble metals (Pt 21 and Au metals 22…”

Ethane (C 2 H 6 ) is a main component of natural gas and a notable contributor to photochemical pollution and ozone production in the atmosphere. It is important to convert ethane to useful chemicals. The photocatalytic conversion of ethane is promising but challenging. As the first review article in this area, we summarize the recent important progresses in photocatalytic ethane conversion, with an emphasis on (1) homogeneously functionalization and (2) heterogeneously partial oxidation of ethane. Furthermore, the challenges and future directions are provided for the photocatalytic conversion of ethane.

Weak Interactions Initiate C−H and C−C Bond Dissociation of Ethane on Nb_n⁺ Clusters

The conversion of ethane into value-added chemicals under ambient conditions has attracted much attention but the mechanisms remain not fully understood. Here we report a study on the reaction of ethane with thermalized Nb n + clusters based on a multiple-ion laminar flow tube reactor combined with a triple quadrupole mass spectrometer (MIFT-TQMS). It is found that ethane reacts with Nb n + clusters to form both products of dehydrogenation and methane-removal (oddcarbon products). Combined with density functional theory (DFT) calculations, we studied the reaction mechanisms of the CÀ C bond activation and CÀ H bond cleavage on the Nb n + clusters. It is unveiled that hydrogen atom transfer (HAT) initiates the reaction process, giving rise to the formation of NbÀ C bonds and an elongated CÀ C distance in the HNb n + CH 2 CH 3 motif. Subsequent reactions allow for CÀ C bond activation and a competitive HAT process which is associated with CH 4 removal or H 2 release, resulting in the production of the observed carbides.
