Recently, it is required to develop the technologies of creating, buildup, and saving of energy. One of the possible system for the utilization of low waste heat is the water adsorption heat pump (WAHP). In this study, we aimed to develop a high-capacity porous carbon adsorbent for WAHP, on which the water adsorption isotherm shows steep and large uptake at low relative pressure where is the operation pressure range of WAHP. The prepared porous carbon materials were controlled the pore properties and doped the nitrogen atoms into the carbon matrices. It was successful to develop the prepared N-doped porous carbon materials which show five times higher water adsorbed amount difference at low relative pressure range comparing with the non-doped porous carbon materials, as an adsorbent for WAHP.

最近，需要开发创造，积累和节省能源的技术。使用低废热的可能系统之一是水吸附热泵（WAHP）。在这项研究中，我们旨在为WAHP开发高容量的多孔碳吸附剂，在该碳中，水吸附等温线在低相对压力下显示出陡峭而大的吸收，而WAHP的操作压力范围是WAHP的操作压力范围。将制备的多孔碳材料控制在孔特性中，并将氮原子掺入碳矩阵中。成功开发制备的N掺杂的多孔碳材料，该碳材料在低相对压力范围内与非掺杂多孔碳材料相比，在低相对压力范围内吸附量差五倍，作为WAHP的吸附剂。
