Article Synopsis
- Researchers extensively study dihydrogen complexes in molecular science, particularly in homogeneous and enzymatic catalysis, but there's limited experimental evidence for their counterparts in heterogeneous catalysis due to complex material surfaces and characterization challenges.
- Using advanced high-pressure operando solid-state NMR technology, this study presents the first clear observation of activated dihydrogen binding on a reduced ceria catalyst linked to surface oxygen vacancies.
- The findings indicate a direct relationship between ceria surface reduction and dihydrogen binding, with NMR analysis showing that bound dihydrogen plays a crucial role in a room-temperature ethylene hydrogenation reaction, which could enhance understanding of hydrogenation mechanisms in solid catalysts.
Gel fracturing fluid is the optimum fracturing fluid for proppant suspension, which is commonly applied in deep reservoir hydraulic fracturing. The content of polymers and crosslinkers in gel fracturing fluid is usually high to meet the needs of high-temperature resistance, leading to high costs and reservoir permeability damage caused by incomplete gel-breaking. In this paper, a supramolecular reinforced gel (SRG) fracturing fluid was constructed by strengthening the supramolecular force between polymers.
