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

BaZrS_3的固相合成：将BaS和ZrS_2在硫脲（TU）存在和不存在的情况下一起研磨，并在250 ℃-350 ℃左右加热混合粉末，得到黑色粉末。溶剂热合成：BaCl_2、ZrCl_4和硫脲在不同的溶剂体系和不同的温度下进行。己烷中的BaCl 2 + Z2 Cl 4 + TU（高压釜）：XRD显示没有与BZrS 3匹配的峰。在乙醇和水中的BaCl 2 + Z2 Cl 4 + TU（在高压釜中）：获得黑色但无定形的粉末。BaCl 2 + ZrCl 4 +TU在乙二胺（EDA）中（高压釜）：黑色粉末但无定形BaS + ZrS + EDA +乙二硫醇（EDT）（高压釜，180 ℃）：黑色粉末但无定形。BaCl 2 + ZrCl 4 +TU的DMSO溶液（高压灭菌器，230 ℃/40 h）：黑色粉末，但无定形
