The liquid-phase furfural （FAL） hydrogenation to furfuryl alcohol （FOL） and tetrahydrofurfuryl alcohol （THFOL） was investigated using sulfonate group （-SO3H） grafted activated carbon （AC） supported Ni catalyst, which was prepared and activated simultaneously by liquid phase reduction method. This functionalized nickel catalyst demonstrated an enhanced catalytic performance for selective hydrogenation of FAL, in which almost 100% FOL （〈80℃） and THFOL （〉100℃） selectivity with complete conversion was obtained, respectively. More importantly, the conversion of transfer hydrogenation of FAL to FOL also can reach almost 100% under optimal conditions （140℃, 4.0h）. The effect of -SO3H was evaluated and systematically analyzed by the combination of reaction performance and physico-chemical characterizations. Cycling test proved the prepared catalyst could be recycled and reused for several times without noticeably reducing catalytic activity of hvdrogenation.

Developing efficient catalysts with high durability and activity for the oxygen evolution reaction(OER)is imperative for sustainable energy conversion technologies,including hydrogen generation and CO_(2) reduction,as well as other electrochemical energy storage *** this end,a comprehensive understanding of the mechanism for the water oxidation reaction is ***,a surfactant,nonafluoro-1-butanesulfonate(FBS),was introduced into Ni-Fe layered double hydroxide(Ni Fe-FBS/CFP)via electrochemical deposition on the surface of a carbon fiber paper(CFP)*** as-prepared Ni Fe-FBS/CFP electrode exhibited excellent catalytic activities for OER compared to the Ni-Fe layered double hydroxide based electrode(Ni Fe-LDH/CFP),an excellent stability of 15 h,and an ultralow Tafel slope of 25.8 m V ***,by combining the results of p H-dependent kinetics investigations,chemical probing,proton inventory studies,and isotopic and atom-protontransfer measurements,it was observed that a proton-transfer process controls the reaction rates of both the Ni Fe-LDH and Ni Fe-FBS catalysts,and the residual sulfonate groups serve as proton transfer mediator to accelerate the proton transfer rate.

An alkaline earth metal-organic framework [Ba（Hsip）（H2O）4]n （1, NaH2sip = 5-sulfoisophthalic acid sodium） has been constructed, and characterized by single-crystal X-ray diffraction. In complex 1, each Ba（II） atom coordinates to one ligand Hsip3- and four water molecules with a distorted nine-coordinated monocapped tetragonal antiprism geometry. Each Hsip2- anion acts as a μ3-bridging ligand, in which two carboxylate groups adopt the same bidentate chelating coordinating model and the sulfonate group takes a monodentate coordinating model, resulting in a wave-like two-dimensional network with a （6, 3） topological structure. The two-dimensional networks are further linked by O–H···O to form a three-dimensional structure. Luminescent property and thermal stability of complex 1 are investigated. 1 belongs to the orthorhombic system, space group Pna21 with a = 7.3333（2）, b = 16.7044（3）, c = 10.4817（2）, Z = 4, V = 1283.99（5）3, Mr = 453.58, Dc = 2.346 g/cm3, F（000） = 880, μ = 3.314 mm–1, the final R = 0.0261 and wR = 0.0592 for 2425 observed reflections with I 2σ（I）.

An interesting metal-organic framework(MOF) PFC-31 was synthesized by a simple solvothermal reaction. X-ray crystallography reveals that PFC-31 crystallizes in monoclinic system, space group P21/c with a = 6.8410(17), b = 20.123(5), c = 7.689(2) ?, β = 104.239(7)°, V = 1026.0(5) ?3, Z = 2, C16 H22 CuN4 O8 S2, Mr = 526.03, μ = 1.322 mm-1, Dc = 1.703 g/cm3, F(000) = 542, GOOF = 1.214, R = 0.0975 and w R = 0.2324. According to X-ray analysis, PFC-31 shows one-dimensional chain constructed by Cu(Ⅱ) centers coordinating with two pyridine groups, two sulfonate groups and two DMF molecules. Owing to the orderly functionalized sulfonate group and Lewis metal sites, PFC-31 exhibits good catalytic capability for CO2 cycloaddition of epoxide under normal pressure and temperature.
