“…Among them, a very important direction is to use solar energy . Therefore, researches on photocatalytic degradation of pollutants has attracted increasing attentions, including direct use of sunlight and ultraviolet light in recent years . Semiconductor photocatalysts can be directly driven by light, which are considered to be an ideal technology for treating environmental pollution and developing new energy sources.…”

Residual pollutants in the water treatment process restrict the advanced treatment and purification of wastewater, because most of them have stable structures, and some are not easily to be enriched. Photocatalytic oxidation technology can directly use solar energy to drive a series of chemical reactions, which has advantages such as low energy consumption, mild reaction conditions and rarely secondary pollution. It is an effective way to solve the organic pollution problem in wastewater treatment. The key to this process is to find and design efficient photocatalysts. The current photocatalytic materials mainly include inorganic semiconductors and metal organic frameworks (MOFs). They have been studied for pollutants degradation, hydrogen evolution, CO2 reduction, and organic transformation. But, most of these catalysts have not been used in real application. In this paper, recent research advances in MOFs photocatalysts and the key factors affecting their photocatalytic efficiency were critically reviewed. It is believed that the pursuit of more efficient photocatalyst needs to be considered from the adsorption‐photocatalytic mechanism, redox‐free radical mechanism, valence‐level regulation mechanism and energy transfer mechanism of photocatalysis. It is very necessary to research and develop nanoscale and quantum level mixed valence MOFs photocatalysts, which are constructed by strong electron‐donating groups.

“…Consequently, the atmosphere [11][12][13][14][15][16][17][18][19][20] and the pedosphere [21][22][23], especially urban [24][25][26][27][28][29] and industrial soils [24,, are primarily impacted. PAHs can also be transferred from soil to groundwater but the extent of this process is limited because of their low aqueous solubility.…”

“…According to CRU -world coke production will rise and the estimated production in 2017 will reach about 793 million tones [5, [6][7][8]. Coking plants creates a threat to the environment [9][10][11]. It is worth noting that coking process gives the possibility of obtaining hydrogen from purified coke oven gas -which contains more than 50 vol.% H2 [12,13].…”

Abstract. The analysis of Carbon Footprint (CF) for technology of hydrogen production from cleaned coke oven gas was performed. On the basis of real data and simulation calculations of the production process of hydrogen from coke gas, emission indicators of carbon dioxide (CF) were calculated. These indicators are associated with net production of electricity and thermal energy and direct emission of carbon dioxide throughout a whole product life cycle. Product life cycle includes: coal extraction and its transportation to a coking plant, the process of coking coal, purification and reforming of coke oven gas, carbon capture and storage. The values were related to 1 Mg of coking blend and to 1 Mg of the hydrogen produced. The calculation is based on the configuration of hydrogen production from coke oven gas for coking technology available on a commercial scale that uses a technology of coke dry quenching (CDQ). The calculations were made using ChemCAD v.6.0.2 simulator for a steady state of technological process. The analysis of carbon footprint was conducted in accordance with the Life Cycle Assessment (LCA).
