Hollow semiconductor nanostructures with direct Z-scheme heterojunction have significant advantages for photocatalytic reactions,and optimizing the interfacial charge transmission of Z-scheme heterojunction is the hinge to achieve excellent solar conversion *** this work,tubular Ni_(1−x)Co_(x)S_(2)-CdS heterostructures with reinforced Z-scheme charge transmission were constructed through an In-metal-organic framework(MOF)templated *** Z-scheme charge transfer mechanism was sufficiently confirmed by combining density functional theory(DFT)calculation,X-ray photoelectron spectroscopy(XPS),surface photovoltage spectroscopy(SPV),and radical testing ***,the use of sodium citrate complexant contributes to the formation of intimate heterointerface,and the Fermi level gap between CdS and NiS_(2)is enlarged through Co doping into NiS_(2),which enhances the built-in electric field and photo-carriers transmission driving force for Ni_(1−x)Co_(x)S_(2)-CdS heterojunction,resulting in an evidently promoted activity toward H2 evolution reaction(HER).Under visible-light(λ>400 nm)irradiation,the Ni_(1−x)Co_(x)S_(2)-CdS composite with 10 mol%Co doping and 80 wt.%CdS(NC_(0.10)S-80%CdS)achieved an outstanding HER rate up to 35.94 mmol·g^(−1)·h^(−1)(corresponding to the apparent quantum efficiency of 34.7%at 420 nm),approximately 76.4 times that of 3 wt.%Pt-loaded CdS and it is much superior to that of most CdS-based photocatalysts ever ***,the good photocatalytic durability of Ni_(1−x)Co_(x)S_(2)-CdS heterostructures was validated by cycling and long-term HER *** work could inspire the development of high-performance Z-scheme heterojunction via optimizing the morphology and interfacial charge transmission.

为探究酶解法制备萝卜籽萝卜硫素的最佳工艺及其消化特性。采用红萝卜种子为原料,以萝卜硫素得率为指标,通过单因素实验和响应面优化试验得出最佳酶解工艺条件。进一步采用体外模拟胃肠消化模型,探究萝卜籽乙酸乙酯提取物萝卜硫素含量及其抗氧化活性的变化规律。得到萝卜籽制备萝卜硫素的最佳酶解条件为:酶解时间22 min,酶解温度40℃,VC添加量0.8 mg/g,在此最佳工艺条件下,萝卜硫素得率为2.11±0.02 mg/g,与预测值(2.14 mg/g)接近,相对误差为1.4%,酶解工艺切实可行。体外消化实验结果表明,胃肠消化液中萝卜硫素保留率分别为79.64%,76.22%;与未消化提取物比较,胃消化液中ABTS+、DPPH、OH三种自由基清除率均显著降低(P0.05)。本研究丰富了酶法制备萝卜硫素方面的研究,将为萝卜籽开发及高附加值利用提供科学依据。
