Facile route to achieve MoSe-NiSe on nickel foam as efficient dual functional electrocatalysts for overall

Frontiers in Energy 2022, Volume 16, Issue 3,   Pages 483-491 doi: 10.1007/s11708-022-0813-0

Abstract: Since the catalytic activity of present nickel-based synthetic selenide is still to be improved, MoSe2-Ni3Se2 was synthesized on nickel foam (NF) (MoSe2-Ni3Se2/NF) by introducing a molybdenum source. After the molybdenum source was introduced, the surface of the catalyst changed from a single-phase structure to a multi-phase structure. The catalyst surface with enriched active sites and the synergistic effect of MoSe2 and Ni3Se2 together enhance the hydrogen evolution reactions (HER), the oxygen evolution reactions (OER), and electrocatalytic total water splitting activity of the catalyst. The overpotential of the MoSe2-Ni3Se2/NF electrocatalyst is only 259 mV and 395 mV at a current density of 100 mA/cm2 for HER and OER, respectively. MoSe2-Ni3Se2/NF with a two-electrode system attains a current density of 10 mA/cm2 at 1.60 V. In addition, the overpotential of HER and OER of MoSe2-Ni3Se2/NF within 80000 s and the decomposition voltage of electrocatalytic total water decomposition hardly changed, showing an extremely strong stability. The improvement of MoSe2-Ni3Se2/NF catalytic activity is attributed to the establishment of the multi-phase structure and the optimized inoculation of the multi-component and multi-interface.

Research on overall encryption adjustment technology of offshore oil field

Zhang Fengjiu,Luo Xianbo,Liu Yingxian,Zhao Chunming

Strategic Study of CAE 2011, Volume 13, Issue 5,   Pages 34-40

Abstract:

Take SZ36-1 oilfield as an example, offshore fields of heavy oil have stepped into later stage in development life and revealed problems gradually for serious injection/production contradiction, big variation for producing reserves in interlayer and plane, much higher for well-controlled reserves, lower for both of oil production rate and oil recovery, changing fast for composite water cut rising and production decline. In view of the challenge for development of offshore fields of heavy oil in China, we put forward the study of comprehensive adjustment for offshore fields in large scale firstly. Because of the special development mode of offshore fields, the proven research thinking and technical route for comprehensive adjustment used by onshore oilfields could not be copied to offshore fields. The research technology of comprehensive adjustment for integral well pattern thickening faces many technical difficulties, so now this research makes a combination of self-characteristics and development mode of SZ36-1 oilfield to put forward a full suite of research thinking and research methods for integral potential tapping and adjustment, and the proposal of comprehensive adjustment for integral well pattern thickening in SZ36-1 oilfield phase I. A water injection well pattern of inverted nine spot is transformed into a well pattern of line drive after pattern adjustment to try a development modes of "direction well & horizontal well network" . The implementation effect of integral well pattern thickening makes a good effect for greatly improved state of water flooding, improved from 80.5 % before adjustment to 91.3 % after adjustment for producing degree of water flooding, forecasting greatly improved recovery for 10.4 %. The technique of adjustment for integral well pattern thickening is sure to be popularized and applied among the similar oilfields.
