ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐

对藏羚羊被毛纤维氨基酸含量进行了测定,结果表明:藏羚羊粗毛中谷氨酸含量比绒毛高约3%,但组氨酸和胱氨酸含量仅为绒毛的66%和15.48%。藏羚羊被毛角蛋白氨基酸的组成与山羊、绵羊被毛纤维相同;但在各种氨基酸的含量比例上有一定的差异:藏羚羊绒毛的组氨酸含量为5.88%,比山羊绒和绵羊毛高约4%;胱氨酸含量为10.60%,高于其他所测山羊的绒和毛;碱性氨基酸与酸性氨基酸含量接近(14.87%,15.23%);藏羚羊绒毛促螺旋蛋白(Paa)含量低于降螺旋蛋白(Daa)。
