Black phosphorus (BP) has attracted tremendous attention as a new two-dimensional semiconductor material with excellent optical and electrical properties. Unfortunately, the mimicking enzyme characteristics of BP have never been investigated. Herein, BP is discovered to exhibit glucose dehydrogenase-like behavior, which can enable catalytic glucose oxidation without any byproducts (e.g., H₂O₂). More importantly, the BP nanosheets also exhibited excellent catalytic performance in broad pH and temperature scope, as well as high stability. This discovery breaks the situation where only glucose oxidase (GOx)-like nanozyme for glucose oxidation is reported. When BP nanosheets were utilized as anodic enzymes for enzymatic biofuel cells (EBFCs), the EBFCs exhibited superior power output and high stability compared with that of bioenzyme-based EBFCs. This work not only develops the application of BP in the nanozyme field but also provides a new viewpoint to construct EBFCs with excellent performance and stability.

基于黑色磷纳米片的葡萄糖脱氢酶样纳米酶，用于高性能生物燃料电池

黑磷（BP）作为一种具有优异光学和电学性质的新型二维半导体材料已引起了极大的关注。不幸的是，从未研究过BP的模拟酶特性。在此，发现BP表现出类似葡萄糖脱氢酶的行为，这可以使葡萄糖催化氧化而没有任何副产物（例如H ₂ O _2）。）。更重要的是，BP纳米片在宽的pH和温度范围内也表现出出色的催化性能以及高稳定性。该发现打破了仅报道了用于葡萄糖氧化的葡萄糖氧化酶（GOx）样纳米酶的情况。当将BP纳米片用作酶促生物燃料电池（EBFC）的阳极酶时，与基于生物酶的EBFC相比，该EBFC表现出优异的功率输出和高稳定性。这项工作不仅开发了BP在纳米酶领域的应用，而且为构建具有优异性能和稳定性的EBFC提供了新的观点。
