Nanoscale titanium nitride TiN is a metallic material that can effectively harvest sunlight over a broad spectral range and produce high local temperatures via the photothermal effect. Nanoscale indium oxide-hydroxide, In O (OH) , is a semiconducting material capable of photocatalyzing the hydrogenation of gaseous CO ; however, its wide electronic bandgap limits its absorption of photons to the ultraviolet region of the solar spectrum. Herein, the benefits of both nanomaterials in a ternary heterostructure: TiN@TiO @In O (OH) are combined. This heterostructured material synergistically couples the metallic TiN and semiconducting In O (OH) phases via an interfacial semiconducting TiO layer, allowing it to drive the light-assisted reverse water gas shift reaction at a conversion rate greatly surpassing that of its individual components or any binary combinations thereof.
纳米级氮化钛(TiN)是一种金属材料,能够在较宽的光谱范围内有效收集太阳光,并通过光热效应产生较高的局部温度。纳米级氢氧化铟氧化物(InO(OH))是一种能够光催化气态CO加氢的半导体材料;然而,其较宽的电子带隙将其对光子的吸收限制在太阳光谱的紫外区域。在此,三元异质结构TiN@TiO@InO(OH)结合了这两种纳米材料的优点。这种异质结构材料通过界面半导体TiO层将金属TiN相和半导体InO(OH)相协同耦合,使其能够以大大超过其单个组分或任何二元组合的转化率驱动光辅助逆水煤气变换反应。
