For supported metal catalyst systems,the impact on catalysis originates from the interaction between metal nanoparticles and their support.Metal-support interactions (MSI) can change electronic properties,geometric morphologies,or chemical compositions of metal nanoparticles to make active sites have specific properties and catalytic activities.Fischer-Tropsch synthesis (FTS) is one of the most effective ways to convert cheap non-petroleum-based carbon sources into high value-added chemicals or ultra-clean liquid fuels.In this review,we summarize and classify the impact of MSI on the catalytic activity,selectivity and stability of FTS catalysts.The strategies to tune MSI are introduced in detail,and the recent development of high-efficiency FTS catalysts through the manipulation of SMI strategies has been high-lighted.It is emphasized that the active metal sites,which are endowed with special functions by MSI,can change the strength of adsorption bond of adsorbates,consequently controlling the product distribution.

Due to the high salt content of coal chemical wastewater,pipeline fouling often occurs during wastew-ater treatment.Fouling will cause the diameter of the pipe to shrink or even block,which is not conducive to the safe and stable operation of the wastewat
The coronavirus disease 2019 (COVID-19) pandemic has led to a great demand on the personal protection products such as reusable masks.As a key raw material for masks,meltblown fabrics play an important role in rejection of aerosols.However,the electrostat
The simultaneous CO2 capture and heat storage performances of the modified carbide slag with by-product of biodiesel were investigated in the process coupled calcium looping and CaO/Ca(OH)2 thermo-chemical heat storage using air as the heat transfer fluid
Five kinds of BZSM-5 molecular sieve with different Si/B ratio and a SiZSM-5 molecular sieve were pre-pared by hydrothermal synthesis method followed by acid exchange and pelletization.The samples were characterized by XRD,SEM,FT-IR,ICP,low temperature N2
The characteristics of the energy structure of rich coal,less oil and less gas,coupling with a high external dependence on oil and natural gas and the emphasis on the efficient and clean utilisation of coal,have brought opportunities for coal chemical ind
