The issue of formaldehyde pollution in indoor building materials was receiving increasing attention from scholars. With the increasing number of research cases on building materials, a systematic evaluation of the effectiveness of existing representative technologies was crucial for the future development of building materials. Adhesives and formaldehyde scavengers were common additive materials in building materials. The effects brought by the technological innovation of these two technologies were more cost-effective and feasible compared to the updating of building materials themselves. This article reviewed the research progress of adhesive and formaldehyde scavenger technologies for three types of building materials (wood-based materials, coatings, and insulation materials) since 2000, totaling 300 articles. It outlined the key technological advancements of each development stage and included a meta-analysis of 80 selected studies to evaluate the effectiveness of these technologies in reducing formaldehyde emissions. The meta-analysis results indicated that, among all studied adhesives, natural plant-based and bio-based adhesives were the most effective in reducing formaldehyde emissions, achieving an overall reduction rate of 91%-94%. For formaldehyde scavengers, nanomaterials, particularly graphene and titanium dioxide, performed the highest effectiveness in reducing formaldehyde emissions, with an overall reduction rate of 97%-98%. The issue of light supply was the main bottleneck for the technological breakthroughs. The combination of degradation materials and adsorption materials for formaldehyde scavengers was currently a research hotspot, and the combination of adhesives and scavengers was also a future research direction.
室内建筑材料中的甲醛污染问题日益受到学者的关注。随着建筑材料研究案例的不断增加，对现有代表性技术的有效性进行系统评估对于建筑材料的未来发展至关重要。胶粘剂和甲醛清除剂是建筑材料中常见的添加剂材料。与建筑材料本身的更新相比，这两种技术的技术创新所带来的效果更具成本效益且可行。本文综述了自2000年以来针对三种建筑材料（木质材料、涂料和保温材料）的胶粘剂和甲醛清除剂技术的研究进展，共300篇文章。概述了每个发展阶段的关键技术进步，并对80项选定研究进行了荟萃分析，以评估这些技术在减少甲醛排放方面的有效性。荟萃分析结果表明，在所有研究的胶粘剂中，天然植物基和生物基胶粘剂在减少甲醛排放方面最有效，总体减少率为91%-94%。对于甲醛清除剂，纳米材料，特别是石墨烯和二氧化钛，在减少甲醛排放方面效果最佳，总体减少率为97%-98%。光照问题是技术突破的主要瓶颈。甲醛清除剂的降解材料和吸附材料的组合目前是一个研究热点，胶粘剂和清除剂的组合也是未来的研究方向。
