“…In the nature, the carrying capacity and self‐regulation of environment is limited, and excessive CO 2 emission has led to greenhouse effect, global warming, sea level rise and other problems that threaten human production and life [13] . More than that, with continuous exploitation of fossil energy sources, the world‘s fossil energy reserves have been gradually depleted [14] . To circumvent these difficulties, researchers have devoted to the conversion of CO 2 to available fuels.…”

Efficient conversion of CO2 to valuable fuels is a desired approach to reduce global warming effect and remit sustained fossil fuel demand. Metal–organic frameworks (MOFs), a class of crystalline porous materials with unique features, have been widely studied for potential applications in varied fields. Recently, photo/electrocatalytic reduction of CO2 to two or more carbons (C2+) products has attracted extensive attention because of their higher market values than one carbon (C1). However, the major products of CO2 reduction currently are carbon monoxide, formate, or methane, which are all typical C1 products. Generally, for photocatalytic reduction of CO2 system, relatively low efficiency of electron transfer with inadequate capability results sluggish kinetics of C−C coupling. And for electrocatalysis, high current densities curtail the stability, which limits selectivity towards C2+ products. In this review, we provide very latest reports that have make some breakthroughs to overcome the above difficulties in photo/electrocatalytic reduction of CO2 to C2+ products using MOF‐based materials. Special emphases are given on design strategies of synthetic MOF‐based catalysts and the mechanisms of catalytic CO2 to C2+ products. The challenges and prospects of photo/electrocatalytic reduction of CO2 to C2+ products associated with MOF‐based materials are also discussed.

“…It is worth mentioning that the wide introduction of RES and carbon dioxide capturing systems is limited by the high prices of "green" technology [4,5]. At the same time, today there are alternative ways to reduce anthropogenic greenhouse gas emissions associated with the development of energy-saving technologies with relatively low cost [6][7][8][9].…”

The most effective and environmentally safe fossil fuel power production facilities are the combined cycle gas turbine (CCGT) ones. Electric efficiency of advanced facilities is up to 58% in Russia and up to 64% abroad. The further improvement of thermal efficiency by increase of the gas turbine inlet temperature (TIT) is limited by performance of heat resistance alloys that are used for the hot gas path components and the cooling system efficiency. An alternative method for the CCGT efficiency improvement is utilization of low potential heat of the heat recovery steam generator (HRSG) exhaust gas in an additional cycle operating on a low-boiling heat carrier. This paper describes a thermodynamic analysis of the transition from binary cycles to trinary ones by integration of the organic Rankine cycle (ORC). A mathematical model of a cooled gas turbine plant (GT) has been developed to carry out calculations of high-temperature energy complexes. Based on the results of mathematical modeling, recommendations were made for the choice of the structure and parameters of the steam turbine cycle, as well as the ORC, to ensure the achievement of the maximum thermal efficiency of trinary plants. It is shown that the transition from a single pressure CCGT to a trinary plant allows the electric power increase from 213.4 MW to 222.7 MW and the net efficiency increase of 2.14%. The trinary power facility has 0.45% higher efficiency than the dual pressure CCGT.

“…The circular economy represents a fundamental pillar for modern business models and sustainable development targets: the mandatory claim "reduce, reuse, recycle" is the answer to the global criticalities of natural resources depletion and waste increase [1,2]. At the same time, energy production and consumption play key roles in the face of challenges of industrialization and rapid population growth: with the depletion of traditional fossil fuels, renewable and low-carbon energy sources have attracted more and more attention for their advantages such as high renewability, great development potential, and possible emissions-mitigation [3,4]. To implement the circular economy in the low-carbon transition, new supply chain opportunities can be explored; at the same time, new dilemmas must be carefully solved through the life-cycle approach, to avoid the environmental burdens shifting [5,6].…”
