“…Furthermore, when tested under consecutive illumination cycles ( Figure S7) similar shape and photocurrent intensities were obtained, confirming the photostability of the electrodes. The photochemical stability of the WO 3 electrodes upon long-term irradiation is in agreement with other studies from the literature [50][51][52][53].…”

This work demonstrates the ability of nanoporous carbons to boost the photoelectrochemical activity of hexagonal and monoclinic WO3 towards water oxidation under irradiation. The impact of the carbonaceous phase was strongly dependent on the crystalline structure and morphology of the semiconductor, substantially increasing the activity of WO3 rods with hexagonal phase. The incorporation of increasing amounts of a nanoporous carbon of low functionalization to the WO3 electrodes improved the quantum yield of the reaction and also affected the dynamics of the charge transport, creating a percolation path for the majority carriers. The nanoporous carbon promotes the delocalization of the charge carriers through the graphitic layers. We discuss the incorporation of nanoporous carbons as an interesting strategy for improving the photoelectrochemical performance of nanostructured semiconductor photoelectrodes featuring hindered carrier transport.

“…Drawing inspiration from these works, several nanomaterial-based catalytic systems have been developed which showed high catalytic performance in the oxidative aza-Henry ( Table 1 ) and/or oxidative Mannich reactions ( Table 2 ) of tetrahydroisoquinolines. These include: CuFe 2 O 4 NPs, 13 AuNPore, 14 Fe 3 O 4 @SiO 2 -bipy-[AuCl 2 ][AuCl 4 ], 15 WO 3 –W1, 16 sponge AuNPs, 17 MNPs@eosin Y, 18 and Ru@DAFO@ASMNPs. 19 It is worth mentioning that some of these nanocatalyts were also successfully utilized in the cross-dehydrogenative coupling of tertiary amines with various pronucleophiles such as malononitrile, dialkyl malonate, H-phosphonate diesters, trimethylsilyl cyanide, and indole derivatives.…”

The implementation of non‐noble metals mediated chemistry is a major goal in homogeneous catalysis. Borrowing hydrogen/hydrogen autotransfer (BH/HA) reaction, as a straightforward and sustainable synthetic method, has attracted considerable attention in the development of non‐noble metal catalysts. Herein, we report a tungsten‐catalyzed N‐alkylation reaction of anilines with primary alcohols via BH/HA. This phosphine‐free W(phen)(CO)4 (phen=1,10‐phenthroline) system was demonstrated as a practical and easily accessible in‐situ catalysis for a broad range of amines and alcohols (up to 49 examples, including 16 previously undisclosed products). Notably, this tungsten system can tolerate numerous functional groups, especially the challenging substrates with sterically hindered substituents, or heteroatoms. Mechanistic insights based on experimental and computational studies are also provided.
