Abstract

The possibility of tritium introduction into graphene oxide (GO) by tritium thermal activation method was demonstrated. It was established that, in order to produce the highest possible specific radioactivity, thin films of GO with a thickness of 5.6 mg/m² must be treated with tritium atoms. The experiment conducted at 77 K showed a number of advantages. GO was processed with tritium atoms, the resulting specific activity of [³H]GO reached 2.6 Ci/mg in term of the weight of the initial GO (0.7 Ci/mg after removal of the labile tritium). Specific energy release of [³H]GO with this specific activity is 22.3 W/kg, which is quite sufficient for its application as a component of a nuclear battery.

利用氚热活化法制备高标记氧化石墨烯，并将其应用于核电池的光伏电池中

摘要通过氚热激活法证明了将氚引入氧化石墨烯（GO）的可能性。实验证明，为了产生尽可能高的比放射性，必须用氚原子处理厚度为 5.6 mg/m2 的氧化石墨烯薄膜。在 77 K 温度下进行的实验显示了许多优点。用氚原子处理 GO 后，[3H]GO 的比放射性活度达到 2.6 Ci/mg（按初始 GO 重量计算）（去除易变氚后为 0.7 Ci/mg）。具有这种比活度的[3H]GO 的比能量释放为 22.3 W/kg，这足以将其用作核电池组件。
