Highly selective production of value-added multicarbon(C2+) products via electrochemical CO2reduction reaction（eCO2RR） on polycrystalline copper（Cu） remains ***,the facile surface modification using poly（α-ethyl cyanoacrylate）(PECA) is presented to greatly enhance the C2+selectivity for eCO2RR over polycrystalline Cu,with Faradaic efficiency（FE） towards C2+products increased from30.1% for the Cu electrode to 72.6% for the obtained Cu-PECA electrode at -1.1 V *** hydrogen electrode（RHE）.Given the well-determined FEs towards C2+products,the partial current densities for C2+production could be estimated to be-145.4 mA cm-2for the Cu-PECA electrode at -0.9 V *** in a homemade flow ***-situ spectral characterizations and theoretical calculations reveal that PECA featured with electron-accepting-C≡N and-COOR groups decorated onto the Cu electrode could inhibit the adsorption of *H intermediates and stabilize the *CO intermediates,given the redistributed interfacial electron density and the raised energy level of d-band center（Ed） of Cu active sites,thus facilitating the C-C coupling and then the C2+selective *** study is believed to be guidable to the modification of electrocatalysts and electrodes with polymers to steer the surface adsorption behaviors of reaction intermediates to realize practical eCO2RR towards value-added C2+products with high activity and selectivity.

The coupling factor is used in this study to characterise the combined effect of the heat transfer and resistance characteristics of a rifled tube. Boundary layer theory is utilised to investigate the relationship between the comprehensive coefficient and Reynolds number in two regions, namely, higher and lower than pseudo-critical enthalpy. Results indicate that mass flux exerts a decisive negative influence on the coupling effect, and the impacts of pressure and heat flux are weak. The overall effect decreases rapidly as the mass flux increases, but it increases in the area behind the quasi-critical enthalpy. The coupling effect is also affected by specific heat ratio, thermal acceleration and buoyancy. The correlations of heat transfer and friction resistance are deduced with high precision according to experimental data.
