The hybrid catalyst composed of the B₁₂ complex and rhodium ion (Rh³⁺) modified titanium oxide was synthesized for the visible light-driven B₁₂ inspired catalytic reaction. The hybrid catalyst contains 4.93 × 10⁻⁶ molg⁻¹ of the B₁₂ complex and 5.43 × 10⁻⁵ molg⁻¹ of the Rh(III) ion on the surface of titanium oxide. Visible light irradiation (λ ≧ 420 nm) of the hybrid catalyst in the presence of triethylamine (Et₃N) as a sacrificial reagent showed absorption at 390 nm, typical for the Co(I) state of the B₁₂ complex monitored by diffuse reflectance UV–vis analysis, which imply that electron transfer from the titanium oxide to Co(III) center of the B₁₂ complex occurred by the visible light irradiation. Benzotrichloride was converted to N,N-diethylbenzamide by the visible light irradiation catalyzed by the hybrid catalyst in air at room temperature. Both the conduction band electron and valence band hole of the catalyst were utilized for the reaction to form the amide product. The reaction mechanism of the duet reaction was proposed.

合成了由B _12配合物和铑离子（Rh ³⁺）改性的氧化钛组成的杂化催化剂，用于可见光驱动的B ₁₂激发的催化反应。杂化催化剂在氧化钛表面上含有4.93×10 ^-6 molg ^-1的B ₁₂络合物和5.43×10 ^-5 molg ^-1的Rh（III）离子。在作为牺牲试剂的三乙胺（Et ₃ N）存在下，杂化催化剂的可见光照射（λ≥420 nm）显示出在B ₁₂的Co（I）状态下典型的390 nm吸收。通过漫反射紫外可见光谱分析监测该配合物，这意味着电子从二氧化钛转移到B _12配合物的Co（III）中心是通过可见光辐射发生的。在室温下，在空气中，由杂化催化剂催化的可见光辐射将三氯化苯转化为N，N-二乙基苯甲酰胺。催化剂的导带电子和价带孔均用于反应以形成酰胺产物。提出了二重反应的反应机理。
