The 3D-KSC as supporting materials was used to build 3D-KSC/PCN-333 (Al).
The MP-11 was loaded on 3D-KSC/PCN-333 (Al) used to construct H2O2 biosensors.
The 3D-KSC/PCN-333 (Al) exhibited effectively improved the immobilization of MP-11.
The 3D-KSC/PCN-333 (Al)@MP-11 electrode showed a good performance.
