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.

近年来，需要开发能源的创造、积累和节约技术。水吸附热泵（WAHP）是一种可能的低废热利用系统。在本研究中，我们旨在开发一种用于WAHP的高容量多孔碳吸附剂，其水吸附等温线在低相对压力（即WAHP的操作压力范围）下表现出陡峭且大量的吸收。所制备的多孔碳材料通过控制孔性质并将氮原子掺杂到碳基体中。成功开发了所制备的氮掺杂多孔碳材料，其在低相对压力范围内的水吸附量差异是未掺杂多孔碳材料的五倍，作为WAHP的吸附剂。
