Highly Efficient Dehydrogenation of Formic Acid over a Palladium‐Nanoparticle‐Based Mott–Schottky Photocatalyst

Abstract

Exploiting useful contacts: The exceptional catalytic performance of a photocatalyst composed of Pd nanoparticles and mesoporous carbon nitride for the dehydrogenation of formic acid in water at room temperature to produce H2 gas (see picture) is due to enhanced electron enrichment of the Pd nanoparticles through charge transfer at the interface of the Mott–Schottky contact.

Palladium‐Based Nanomaterials: A Platform to Produce Reactive Oxygen Species for Catalyzing Oxidation Reactions

“…Although most cases in literature have not specifically investigated the behavior of oxygen activation in Pd-based hybrid structures, we can fi nd some clues about how other components in such structures may impact on the effi ciency of oxygen activation. [ 63,64 ] Possible major effects from the hybrid components are listed in Figure 6 a.…”

Ultrasmall palladium nanoparticles supported on amine-functionalized SBA-15 efficiently catalyze hydrogen evolution from formic acid

“…In recent years, various homogeneous catalysts based on metals such as Ru [11][12][13][14] and Ir 15 and heterogeneous catalysts including AuPd/C, 16 AgPd, 17 CoAuPd/C, 18 Pd/ C 3 N 4 19,20 for the dehydrogenation of FA have been reported. Generally, homogeneous catalysts are highly active and exhibit higher turnover frequencies (TOFs) than heterogeneous catalysts for many reactions including formic acid dehydrogenation.…”

“…The rate and amount of total H 2 -release from FA over SBA-15-Amine/Pd were quite good, with an initial TOF of 293 h À1 in 10 min, which is among the highest TOFs for FA dehydrogenation previously reported for other heterogeneous catalysts under ambient conditions without bases. [11][12][13][14][15][16][17][18][19][20] The TOFs of recently developed heterogeneous catalysts without additives at ambient temperature are compared in Table S1 † entries 1-6 and Fig. S5.…”

Facile Morphology Control of Ag Core/Pd Shell Metal Nanoparticles with Sodium Citrate for Hydrogen Production from Formic Acid

“…However, heterogeneous catalysts consisting of single metals often fail to produce sufficient hydrogen from FA, demanding different approaches to design nanoparticles for enhancement of catalytic activity. [16][17][18][19] Fabrication of bimetallic core-shell nanostructures is great interest as one of effective ways to improve catalytic activity of metal catalysts used for hydrogen generation under ambient conditions. 7 16 20 Their unique physical and chemical properties can provide flexibility, stability, or even novel properties as compared with monometallic catalysts.…”
