Hydroxyapatite nanoparticles (HAP NPs) were synthesized by a one‐step hydrothermal method. The surface of HAP NPs was grafted —SH and —COOH chelating groups via in situ surface‐modification with iminodiacetic acid (IDA) and 3‐mercaptopropyl trimethoxysilane (MPS) to afford dual surface‐capped nano‐amendment HAP‐IDA/MPS. The structure of HAP‐IDA/MPS was characterized, and its adsorption performance for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ was evaluated. The total adsorption capacity of 0.10 g HAP‐IDA/MPS nano‐amendment for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ with an initial mass concentration of 20 mg·L^-1 reached 13.7 mg·g^-1, about 4.3 times as much as that of HAP. Notably, HAP‐IDA/MPS nano‐amendment displayed the highest immobilization rate for Hg²⁺, possibly because of its chemical reaction with —SH to form sulfide, possessing the lowest solubility product constant among a variety of metal sulfides.

本实验针对电催化CO₂还原反应，设计了一个利用催化剂和电解液双调控策略促进生成多碳(C₂₊)化合物的实验。该实验设计合成了Ag掺杂CuO(Ag-CuO)作为催化剂，对不同卤素阴离子引入的KHCO₃阴极电解液进行筛选，在H型电解池中利用三电极测试系统进行性能分析。通过考察施加电位、催化剂第二组分(Ag)掺杂、卤素电解液种类和浓度对催化反应性能的影响，筛选出最佳反应体系。本实验内容包含无机化学、物理化学、分析化学等多学科知识和实验操作，在加强学生对化学基础知识理解的同时，培养学生化学类专业核心素养、科学思维以及科研创新能力，提升学生能动性，符合新时代学科发展要求。

在“新工科”背景下，催化化学基础作为化学与化工类专业核心课程，兼具学科交叉性、前沿性和理论与应用结合优势，为科学思维培养提供平台。本文结合课程典型案例，探讨在教学中系统训练学生科学思维，提升其分析、归纳与创新能力，推动其由知识接受者向科学探索者转变，为高年级专业课程融入科学思维培养提供借鉴。
