Synthesis of BaZrS31.Solid-state synthesis of BaZrS3: grinding BaS and ZrS2 together with and without thiourea (TU) and heating the mix powder at around 250oC-350oC, black powder resulted. However, XRD analysis showed no peaks matching with BaZrS3.2.Solvothermal synthesis: BaCl2, ZrCl4 and thiourea in different solvent systems and at different temperatures. BaCl2 +Z2Cl4+ TU in hexane (autoclave): XRD shows no peaks matching with BZrS3. BaCl2 +Z2Cl4+ TU in Ethanol and water (in an autoclave): black color but amorphous powder was obtained. BaCl2+ZrCl4+TU in ethylene diamine (EDA) (autoclave): black powder but amorphous BaS + ZrS + EDA + ethylene dithiol (EDT) (autoclave, 180oC) :black powder but amorphous. BaCl2+ ZrCl4 +TU in DMSO (autoclave, 230oC/40h): black powder but amorphous

固相合成BaZrS3：用硫脲(TU)和不加硫脲(TU)将BaS和ZrS2混合研磨，在250oC-350oC左右加热，得到黑色粉末。溶剂热合成：BaCl2、ZrCl4和硫脲在不同的溶剂体系和不同的温度下合成。BaCl2+Z2Cl4+Tu在正己烷(高压釜)中：X射线衍射峰没有与BZrS3匹配的峰。BaCl2+Z2Cl4+Tu在乙醇和水中(在高压锅中)：黑色，但无定形粉末。BaCl2+ZrCl4+TU在乙二胺(EDA)中(高压锅)：黑色粉末，但无定形BAS+ZRS+EDA+乙二硫醇(EDT)(高压锅，180oC)：黑色粉末，无定形。DMSO(高压灭菌器，230oC/40H)中的BaCl2+ZrCl4+Tu：黑色粉末，但无定形
