Rational Design of Porous Conjugated Polymers and Roles of Residual Palladium for Photocatalytic Hydrogen Production

Developing highly efficient photocatalyts for water splitting is one of the grand challenges in solar energy conversion. Here, we report the rational design and synthesis of porous conjugated polymer (PCP) that photocatalytically generates hydrogen from water splitting. The design mimics natural photosynthetics systems with conjugated polymer component to harvest photons and the transition metal part to facilitate catalytic activities. A series of PCPs have been synthesized with different light harvesting chromophores and transition metal binding bipyridyl (bpy) sites. The photocatalytic activity of these bpy-containing PCPs can be greatly enhanced due to the improved light absorption, better wettability, local ordering structure, and the improved charge separation process. The PCP made of strong and fully conjugated donor chromophore DBD (M4) shows the highest hydrogen production rate at ?33 mumol/h. The results indicate that copolymerization between a strong electron donor and weak electron acceptor into the same polymer chain is a useful strategy for developing efficient photocatalysts. This study also reveals that the residual palladium in the PCP networks plays a key role for the catalytic performance. The hydrogen generation activity of PCP photocatalyst can be further enhanced to 164 mumol/h with an apparent quantum yield of 1.8% at 350 nm by loading 2 wt % of extra platinum cocatalyst.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Formula: C10H6Br2N2, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 15862-18-7

Adduct formation of Dichloridodioxidoniolybdenum(vi) and Methyltrioxidorhenium(vii) with a series of Bidentate Nitrogen donor ligands

The stability of a variety of bidentate N-base adducts of MoO 2Cl2 and (CH3)ReO3 (MTO) was investigated in thf and CH2C12 as solvents. The formation constants were determined from the spectrophotometric data based on 1:1 adduct formation. The adduct formation constants for [MoO2Cl 2L2](L2 = bidentate nitrogen ligand) are 104-106 times higher than those for [(CH 3)ReO3L2] with the same ligands under the same conditions. The adduct stability of both systems is very sensitive to the electronic nature of the ligands and increases with their donor ability. Hammett correlations of the formation constants against sigmagive relatively large negative values for the reaction constants (pRe = -5.9, p Mo = -6.6). The stability is also governed by steric and strain factors. Thus, sterically hindered 6,6′-disubstituted 2,2′ -bipyridines do not form ad ducts with MTO, and only 6,6′-dimethyl- and 6,6′-diphenyl- 2,2′-bipyridines form adducts with MoO2Cl2. However, these adducts are much less stable than other methyl derivatives of 2,2′-bipridine adducts. The steric strain between the two methyl groups in 3,3-dimethy 1-2,2′-bipyridine influences the bipyridine planarity upon complexation and reduces the adduct stability. The thermodynamic parameters (enthalpy and entropy) were determined from temperature-dependence studies. The adduct stability is mainly due to the strongly exothermic binding of the nitrogen-bidentate ligand. The entropy change is small and has little effect on adduct stability.Wiley-VCH Verlag GmbH & Co, KGaA.
