Simultaneous photocatalytic H₂generation and organic synthesis over crystalline–amorphous Pd nanocube decorated Cs₃Bi₂Br₉

Abstract

Cs3Bi2Br9 decorated with crystalline-amorphous Pd nanocubes as cocatalyst is reported to photocatalytically coproduce ca. 1400 μmol h−1 g−1 of H2 and benzaldehyde from the selective benzyl alcohol oxidation. This route...

Crystal structure engineering of metal halide perovskites for photocatalytic organic synthesis

“…Next, Cs 3 Bi 2 Br 9 and Cs 3 BiBr 6 were synthesized (see ESI †) for further analysis. 18 XRD results in Fig. 2A show that both Cs 3 Bi 2 Br 9 and Cs 3 BiBr 6 exhibit strong diffraction peaks, without shift compared to theoretical data.…”

In situconstruction of graphdiyne based heterojunctions by a deprotection-free approach for photocatalytic hydrogen generation

“…3b), where the peaks located at 284.5 and 286.0 eV can be assigned to CC (sp 2 ) and C–O, while the peaks at 287.5 and 288 eV can be attributed to C–N (sp 2 ) in C 3 N 4 , respectively. 21,36–39 The N 1s XPS spectra of GDY@C 3 N 4 can also be deconvoluted into four sub-peaks at 399.1 eV for sp 2 -hybridized N in the C–N heterocycle (CN–C), 400.7 eV for sp 3 -hybridized N ( N –C 3 ), 401.7 eV for amino groups (–NH) and 405.1 eV for charge effects, respectively (Fig. 3c).…”

“…Photocatalytic solar-to-hydrogen energy conversion is one of the most promising technologies to simultaneously solve global environmental issues and energy crises. [1][2][3][4] Along with the intensive research in the development of efficient and costeffective photocatalysts, [5][6][7] carbon-based heterojunction photocatalysts have emerged as a new class of alternative materials. 6 Graphdiyne (GDY), consisting of both sp 2 and sp hybridized carbons, is a rising-star 2D carbon material.…”

Ultrathin corrugated nanowire TiO2 as a versatile photoanode platform for boosting photoelectrochemical alcohol and water oxidation

“…The weak oxidant, O 2 ˙ − , cleaved the O–H bond in the C 6 H 5 -CHOH˙* that was further converted to BAD as the sole oxidized product, resulting in highly selective oxidation of BA to BAD. 35–41…”

“…The weak oxidant, O 2 c − , cleaved the O-H bond in the C 6 H 5 -CHOHc* that was further converted to BAD as the sole oxidized product, resulting in highly selective oxidation of BA to BAD. [35][36][37][38][39][40][41] Fig. 4C and D show the reason why the performance of UCW-TiO 2 PEC BA oxidation is better than that of NPTiO 2 .…”
