甜玉米提取物把二氧化碳矿化成纳米水锌矿：《科学报告》常温常压得单相晶体、平均晶粒 38.5 纳米、漫反射率逾 95%
一项 2026 年 11 月 11 日刊于《科学报告》的研究首次演示了用甜玉米水提取物把二氧化碳生物启发矿化为单相水锌矿。水锌矿的化学式为 Zn5(CO3)2(OH)6，研究使用甜玉米（Zea mays saccharata）的水提取物作螯合剂与封端剂，作者为 Masibi 等人。
工艺条件方面，该方法在环境条件下进行，即室温与常压，得到的单相结晶水锌矿平均晶粒尺寸为 38.5 纳米。作者表示，通过引入碳酸根，这一过程为二氧化碳捕集提供了一条可能路径。
表征方面，研究用紫外可见漫反射、光致发光、傅里叶变换红外、X 射线衍射与扫描电镜能谱等手段验证产物。结果显示，这种生物工程纳米水锌矿漫反射率逾 95%，并有有效的蓝光发光，最大发射波长约 457.3 纳米。
电化学方面，研究在 1 摩尔每升氢氧化钠电解液中用循环伏安与电化学阻抗谱考察其电化学性质。致谢部分载明，作者之一获南非国家研究基金会资助，资助编号 PSTD240202203521。论文数字识别码为 10.1038/s41598-026-79911-2。
Sweet Corn Extract Mineralizes Carbon Dioxide into Nanoscaled Hydrozincite: Single-Phase Crystals at Ambient Conditions with an Average Crystallite Size of 38.5 Nanometers and Diffuse Reflectance over 95 Percent, in Scientific Reports
A study published in Scientific Reports on November 11, 2026 demonstrated for the first time the bio-inspired mineralization of carbon dioxide to single-phase hydrozincite, Zn5(CO3)2(OH)6, using aqueous extracts of sweet corn, Zea mays saccharata. The extract served as a successful chelating and capping agent. The authors are Masibi and colleagues.
Under ambient circumstances, at room temperature and atmospheric pressure, the method produced single-phase crystalline hydrozincite with an average crystallite size of 38.5 nanometers. The authors state that, by including carbonate, the process provides a possible route for carbon dioxide capture.
Characterization by ultraviolet-visible diffuse reflectance, photoluminescence, Fourier-transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy with energy-dispersive spectroscopy showed that the bio-engineered nanoscaled hydrozincite is a highly reflective material, with diffuse reflectance over 95 percent, and an effective blue luminescence with maximum emission at about 457.3 nanometers.
Electrochemical properties were investigated in 1 molar sodium hydroxide electrolyte using cyclic voltammetry and electrochemical impedance spectroscopy.
