这项工作旨在促进将胺化化合物浸渍或接枝到二氧化硅基质上的标准化技术的发展,这些技术通常在文献中被广泛描述。将详细讨论溶剂、底物、胺的具体用量以及其他重要实验参数的值。

NIST的科学家正在开发关键的测量科学和基准材料,以加速创新,并探索及时、有效和可扩展的直接空气捕获(DAC),用于从大气中去除二氧化碳。这项工作的重点是推广用于DAC应用的胺官能化二氧化硅复合材料的制备、测量和报告的最佳实践。该协议通过提供明确的指南和条件,同时确定关键步骤,解决了 DAC 材料的突出研究挑战和可重复的合成程序。

此外,我们的目标是通过明确记录特定的吸附实验参数,对这些材料的二氧化碳能力进行有意义的比较。我们正在将工作转向表征基准材料和开发标准技术,以提高报告结果的可比性和可信度。
