Designing a Z-scheme heterojunction is of great significance to achieve high separation of photogenerated carriers and strong photo-redox properties of two semiconductor materials. In photosynthesis, the effects of photocatalytic electrolytes (adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH)) on chemical energy has attracted numerous interests. In this case, developing photocatalytic electrolytes with more active site and efficient charge extraction and separation would be beneficial for superior photocatalytic activity in Z-scheme system. Herein, we synthesized a Black/Red (BP/RP) phosphorus Z-scheme hybrid via a feasible two-steps sonochemical method, and the adding photocatalytic electrolytes ATP and NADPH in KOH solution endow the system with new vitality in photocatalysis. Consequently, photoelectrochemical (PEC) tests demonstrated the as-prepared BP/RP Z-scheme hybrid exhibits enhanced photocurrent of 9 μA/cm² at 0.5 V compared to the sole RP, while adding NADPH and ATP, the photocurrent of BP/RP Z-scheme hybrid shows dramatic increment of 30 μA cm⁻² at a bias potential of 0.6 V. The improved photocatalytic activity is ascribed to the abundant active sites, higher carrier mobility of the BP/RP Z-scheme system, as well as the efficient photogenerated carrier separation and the prolonged lifetime of photocatalytic electrolytes. This work demonstrated the photocatalytic electrolytes can meet the unity of coordination and efficiency of achieving efficient PEC catalytic in the Z-Scheme system, and provides positive ideas for the possibility and superiority for other 2D materials in the field of ultrafast Photonics, photodetectors, etc.

设计Z型异质结对于实现光生载流子的高度分离和两种半导体材料的强光氧化还原特性具有重要意义。在光合作用中，光催化电解质（三磷酸腺苷（ATP）和烟酰胺腺嘌呤二核苷酸磷酸（NADPH））对化学能的影响吸引了许多兴趣。在这种情况下，开发具有更多活性位点和有效电荷提取和分离的光催化电解质将有利于Z方案系统中优异的光催化活性。在这里，我们通过可行的两步声化学方法合成了黑/红（BP / RP）磷Z-方案杂化体，并且在KOH溶液中添加光催化电解质ATP和NADPH使该系统在光催化中具有新的生命力。所以，与单独的RP相比，在0.5 V时为²，在添加NADPH和ATP的同时，BP / RP Z方案杂化体的光电流 在0.6 V的偏压下显示出30μAcm ^-2的急剧增加。归因于光催化活性的提高丰富的活性位点，BP / RP Z方案系统更高的载流子迁移率，以及有效的光生载流子分离和光催化电解质的延长使用寿命。这项工作证明了光催化电解质可以满足Z-Scheme系统中实现高效PEC催化的协调和效率的统一，并为超快光子学，光电探测器等领域中其他2D材料的可能性和优越性提供了积极的想法。
