我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。本品属于绿色替代产品的赋能型产品，符合“节能设计”原则。高浓度氧化石墨烯片提供结合电极材料和实现3D打印所需的粘度。以水为绿色溶剂使得该水性墨水系统可用于安全、低成本的加工和干燥。点击此处以获取更多信息。

氧化石墨烯（GO）是一种单原子厚的二维碳材料，由于其独特的结构和形态特征，具有优异的热、机械和电学性能。氧化石墨烯可以很容易地分散在水性和极性有机溶剂中，以促进其实际应用。它可以用改良的 Hummer’s 方法合成。它可以应用于药物递送、储能、油水分离、固定化催化、脱盐和太阳能电池等领域。

应用

由于含氧官能团的存在和酸性，氧化石墨烯既可以作为碳催化剂，也可以作为各种催化活性物质的支撑支架。氧化石墨烯可以促进许多有机转化，如硫化物、烯烃和各种碳氢化合物的氧化、Friedel–Crafts 反应、Aza–Michael 加成、缩合和开环聚合。

它可用作有机溶剂中生物催化的载体。例如，羧基官能化的氧化石墨烯可以作为固定化解脂耶氏酵母脂肪酶的载体。该固定化酶在有机溶剂中对外消旋化合物具有较高的溶解效率。

它也可用作有机光伏电池中的空穴传输层。

特点和优势

良好的溶液可加工性
亲水性强，易于分散在水中
生产成本低
存在丰富的含活性氧官能团
它可以很容易地功能化

表面积大、化学稳定性高、载流子性能好。[1]

制备说明

产物可能随时间聚集形成较大的颗粒。如果需要单层氧化石墨烯，在使用前可进行超声处理。

Chemically derived graphene oxide: towards large-area thin-film electronics and optoelectronics.

Goki Eda et al.

Advanced materials (Deerfield Beach, Fla.), 22(22), 2392-2415 (2010-05-01)

Chemically derived graphene oxide (GO) possesses a unique set of properties arising from oxygen functional groups that are introduced during chemical exfoliation of graphite. Large-area thin-film deposition of GO, enabled by its solubility in a variety of solvents, offers a

Graphene is a promising candidate to complement brittle and expensive transparent conducting oxides. Nevertheless, previous research efforts have paid little attention to reduced graphene, which can be of great benefit due to low-cost solution processing without substrate transfer. Here we

Molecular basis for metabolite channeling in a ring opening enzyme of the phenylacetate degradation pathway.

Nitish Sathyanarayanan et al.

Nature communications, 10(1), 4127-4127 (2019-09-13)

Substrate channeling is a mechanism for the internal transfer of hydrophobic, unstable or toxic intermediates from the active site of one enzyme to another. Such transfer has previously been described to be mediated by a hydrophobic tunnel, the use of
